Was experimenting with halftone effects after watching this video and it almost has spiderverse vibes honestly. I actually learned some neat things about why printers use CMYK instead of just CMY so I thought I'd share !!
So in our optimal little computer space, Cyan (0,255,255), Magenta (255,0,255) and Yellow (255,255,0) all multiplied together gives us a perfect black (0,0,0) Awesome! The issue is that ink colors irl arent exactly perfect like this, and color is a bit more complicated irl compared to how computers represent it, so they aren't the greatest at combining into black if they aren't those perfect CMY values:
Left: CMY
Right: CMYK
(thats not even black, its a dark blue in the original image but dark colors just look so much richer)
An important step to make sure you arent doubling up on the black values though is to divide the image by it's own "value" (the max of all 3 color channels) that way the value is equal to 1 everywhere, and you're letting the black ink take care of the value on its own.
Left: CMY (normalized value)
Middle: K (black)
Right: Combined
Now obviously the grids of dots cant be aligned perfectly with each other because you'd just get a bunch of black dots in unwanted areas, but if the grids are misaligned, then some dots become more prominent than others which tints the whole image. This was an issue because older printing methods didn't have great accuracy and these grids were often misaligned.
The solution was to rotate these grids such that they can move around freely while getting rid of that tint effect if they aren't perfectly aligned :D
(I have no idea how they came up with these angles but that might be something to look into in the future who knows)
SPEAKING OF MISALIGNMENT
I wanted to implement that in my own filter to get some cool effects, and I discovered another reason CMYK is better than CMY for lots of stuff !!
With CMY, you're relying on the combination of 3 color channels to make the color black. This means if you have thin lines or just details in general, misalignment can make those details very fuzzy. Since CMYK uses a single color of ink to handle value, it reduces color fringing and improves clarity a lot even if you have the exact same misalignment as CMY!
Left: CMY
Right: You guessed it! CMYK
(yes these comparisons have the exact same color misalignment, the only difference is using a fourth ink color for black)
ANYWAY I just thought there was a lot of cool information in this tiny little day project, I also just think it looks really neat and wanted to share what I learned :3c
EDITING BECAUSE THERE'S ONE MORE THING I WANTED TO ADD
So, I talked about how to get K in addition to CMY instead of just CMY, but how exactly do you separate CMY from an image in the first place?
Well, CMY is a subtractive color space, meaning the "absence of color" is white, compared to RGB where it's black. This makes sense because ofc ink is printed on white paper. You can use dot product to get the "similarity" between two vectors, and this can be used to separate RGB actually! Using the dot product of a color and red (255,0,0) will give you just the red values of the image. This is cool though because if we get the dot product of our image and the color cyan (0,255,255), we can get the cyan values from our image too! If we first divide our colors by their value to separate the value from them, then separate CMY using those dot product values, and using K for our final black color value, our individual color passes end up looking like this:
While it's called a "subtractive" color space, I find it more intuitive to treat white as the absence of color here, and then multiply all these passes together. It makes it much easier to understand how the colors are combined imo.
Notice how cyan is the opposite of red: (255,0,0) vs (0,255,255) and magenta and yellow are the opposites of green and blue respectively! This means you can actually kinda get away with separating the RGB values and just inverting some stuff to optimize this, but this example is much more intuitive and readable so I won't go too deep into that.
THANKS FOR READING
I know it's a very long post but I hope people find it interesting! I try my best to explain things in a clear and concise way :3
oh thank you I realized I should probably add an eyestrain tag

Aah!! As the strange anon who requested Naoya. I gotta say I totally agree with these headcanons! You got him perfect lol basically a d**k..unless your super hot, don't speak and magically anticipate exactly what he wants when he wants it...in which case he's slightly less of a d**k. Ooh please do gojo headcanons now I'm addicted haha
lmfao strange anon 😭😭 but fr you’re right tho, naoya would usually be the type to say “you look prettier with your mouth shut, keep it that way”.
♡.°₊Satoru is the type of man to…ˎˊ˗
content: jjk headcanons; half sfw/half nsfw; afab!reader; i love my cutie patootie boo boo bear pookie blue eyed king gojo >.<!!
n/a: i love this man sm, I already kinda did hcs of him before, but they were mostly nsfw, so i really scratched my head to not repeat them as best as i could.
these are my hcs! feel free to agree or disagree :b any request/interaction supporting this post is very much appreciated <3
sfw ver! ୨ৎ
Satoru is the type of man to… have gifting as his love language. Aside from being extra clingy, he’s the type to gift you stuff at least twice a week. They’re mostly things that reminds him of you or that he thinks you’d like (even though he might fail sometimes when it comes to treats, since he has a sweet tooth it may or may not be too sweet for you).
Satoru is the type of man to… act sassy/petty when jealous. Satoru isn’t the type to make a scene (at least not directed to you) or generally be ill-tempered/insecure. However, whenever he sees someone who looks at you in a different way than the others or tries to engage in a conversation with you that seems too intimate to be friendly, Satoru is the type of man to walk up to you and hug you from behind, giving you neck kisses. While you may think him being overly cuddly with you is normal due to his clingy character, Satoru is doing all that on purpose to let whoever is ‘bothering’ you that you already have someone else, with a damn smug smile plastered on his face (and maintaining direct eye contact with the stranger).
giggled and kicked my feet while writing this.
Satoru is the type of man to… try new things for you. So it is more than obvious that Satoru is old money rich. Like this dude was RICH RICH and spoiled rotten since he was child, not to mention that he’s a special grade sorcerer (he basically gets bank as a salary), therefore he’s accustomed to getting the finest things, either for you or for himself. What may seem expensive to you is probably normal for him. That doesn’t mean he’s some type of snob or is condescending about middle and working class. Satoru would be the type of be slightly skeptical when you take him to a ‘not so high-end’ restaurant, but since it was a “spot you knew”, it must be good, right? Satoru would be surprised to know that the food in the less wealthy places is sometimes even better than his common luxurious michelin-starred restaurant.
sounds like a cute trope imo
Satoru is the type of man to… taking pictures of you without you realizing it. It’s a hidden hobby of his, he thinks you look prettier when you’re distracted. Satoru has certain photo albums in his phone gallery that require a password, that is because you’d probably be embarrassed if you ever found out, but he really likes them, in the least creepy way.
Satoru is the type of man to… pretend not to know certain things as long as he has something to approach you with. Despite being good at pretty much everything, Satoru will lie and pretend to be terrible at something you are specifically passionate about so that you can teach him because he loves to see you get excited about sharing your hobbies and likes with others. His subtle way of knowing about you and collecting information he needs for when he wants to ask you out.
nsfw ver! ୨ৎ
Satoru is the type of man to… have public sex. Whether it’s at home or at some expensive restaurant’s washroom, nothing will stop him from pounding his cock balls deep inside you, though the thought of getting caught being freaky in public always gets his adrenaline rushing and his cock throbbing.
Satoru is the type of man to… have you modeling the lingerie he buys for you. He loves to see how excited you are to show him the little lingerie you bought with his card. But he loves it more when you thank him bouncing on his dick.
Satoru is the type of man to… have phone sex with you when he’s away. Due to his work, he has to sometimes to fly across Japan and this can take a few days before he comes back home. Satoru will call you late at night to ask how your day was then ask you to play with yourself, maybe even do a video call so he can see your pretty ‘o’ face.
Satoru is the type of man to… cover you in hickeys. He takes pride in letting everyone know he fucked you real good last night as well as to mark you as his. It also helps to keep other men from you, so he does this pretty often.
Satoru is the type of man to… fuck you in front of a mirror. Satoru likes to fuck you in doggy as well as to see your fucked out face, so he came up with the solution of placing a mirror in front of his bed so he can plunge his cock deep inside your walls just the way he likes and get to see you roll your eyes to the back of your head as he rearranges your guts. He also gets to look at himself and brag a little. (a little narcissistic from him if you ask me lmao)

I haven't seen any posts about this yet but l've seen some fan art that makes me feel this needs to be said:
Don't forget Leah Sava Jeffries has darker skin when making Annabeth Chase fan art!
She is much closer to Lupita Nyong'o than Zoe Kravitz when it comes to shading, reflection, and complementary color usage :).
Lighting for dark skin is different on light skin. Light skin gets changed by lighting, and dark skin reflects the lighting. Below is a lovely shot of Nyong'o's character from Wakanda Forever in mourning. The filmmakers emphasize the umber qualities of her skin in contrast to the funereal white and (arguably harsh) light across her shoulder below.
Try to pick spots that aren't directly in or near the light, and try mixing 3 or more! You can put it into a color mixer online, or even color pick, lower the opacity, and lay the shades over each other until you find one that fits. And of course, the more 'realistic' you want to go with shading and lighting, the more shades you're going to want to be able to explore vivaciously :D.
Let's take a look at the same 3 beautiful actresses I mentioned at the beginning, with a bad color picked area and a better-ish color picked area. (Please keep in mind, these are not perfect comparisons, as I was not able to find pictures of all 3 actresses under the same kind of lighting.)
Kravitz's has a clear difference between the two, but they aren't too far apart, in comparison to Nyong’o’s and Jeffries’s. Note the dullness in the poorly picked shades as opposed to the better ones. Also keep in mind that while Kravitz has a rosy undertone (at least in that picture - it’s from The Batman, which has stylized coloring) Nyong’o has a slight cool undertone (I can’t pin down quite what, but the picture is definitely not stylized like Kravitz’s).
Jeffries runs more ochre or russet, but neither of those are pink. They are more red than terracotta or umber, but to call Jeffries’s face rosy would be wrong. Err more towards the golden when drawing her.
^^saved an image from a writing tutorial long ago, but can’t seem to find it. If someone recognizes it, I’ll link it.
EDIT: it’s from this post. Thanks @autumnrowancollector ! <3
And also, the darker skin gets, the less likely warm undertones are going to appear. Don't be afraid to use blue or purple or even green on occasion!
Additionally, cool lighting on dark skin is always a win imo.
(I was going to use that picture of Jeffries as Annabeth by the lightning bolt, but then I realized the lighting on her face doesn’t quite match up with where it should hit from that angle, and I realized they kind of just turned everything bluer, so screenshot time!)
(Also if you want another really great live action example, check out anything Aldis Hodge is in, like Leverage and Black Adam)(and of course there’s Spiderverse <3 but I want to post pictures of Hodge)
Now, to here’s a list of more experienced people’s advice:
Black facial features & hair
Shading digitally for a (somewhat) monotone Black character
Stylistic choices and places to start looking for inspiration (besides a search engine).
Coloring Black people’s lips
A better coloration tutorial
Also a nice tutorial for Indigenous skin tones, just in case yall want to draw Piper or use this information for other dark skinned characters :).
EDIT: Some actresses who are closer in skintone to use for Annabeth, provided by the lovely @blackfemmecharacterdependency ! If you can’t find a reference for Jeffries in a specific lighting, maybe check out these ladies’ pictures! It’s a reblog, so scroll down.
TLDR: Don’t make Annabeth pink and pale, make her dark and golden.
