turns out the way paints mix (blue + red = purple) is much more complicated than how light mixes (blue + red = pink) they have to use a little bit of nonlinear modeling to capture this, and "add" paints in this nonlinear latent color space

here's the link scrtwpns.com/mixbox.pdf it's software too

definitely a nice practical and creative application of modern ML concepts and that alone does make the paper really cool but I think their comparison to other applications is very misleading and the result of "we can now finally do realistic pigment mixing" is misrepresented

not a new paper; only new to me

Breakdown of the paper: The paper discusses the issue of color mixing in digital painting software. In real life, when we mix blue and yellow paints, we get a green color. However, in today's painting software, mixing blue and yellow results in a gray color instead. This is

Oh yea, those guys are great; they created a useable version of one of the things Runway can do back in 2018 (the program in question being Ebsynth)

Certainly this is an undisclosed ad for painting software?

The last version of Rebelle implemented this sort of color mixing. It's a lot of fun!

this plus something like a palette that mixes melted filament in controlled ratios would go hard

so cool! also surprising that something as important as this wasn't still solved

"chech republic and secret weapons" this looks quite cool too

This paper is quite a bit out of date. Rebelle now uses this software and has for a few years. youtu.be/Xsqtg2yRl8M?si

This should have been solved 30 years ago. These companies are beyond useless.

Interesting, I wonder if all these companies eventually update the way their pigment mixes and this old style becomes a stylistic relic that can be taken advantage of artists in other way. Much like how old technology is repurposed by contemporary artists for stylistic reasons

Paper by Fiftythree had a color mixer that also tried to replicate what would happen in the real world. Some background info on how they did it can be found in the web archive: web.archive.org/web/2013111601 Looks like the Kubelka-Munk model is pretty much the secret ingredient for all.

Do artists actually prefer the realistic behavior, though? What if you're already used to RGB mixing

Right? I’d love to see a version that makes use of P3 colours too!

this is old and this has still not been merged into krita

The Rebelle example is a little unfair, because you just need to turn on pigment function and you will get a pretty great result.
