Mixbox colour mixing is very realistic

Mixbox: Practical Pigment Mixing for Digital Painting

Hopefully a future version will achieve a similar effect with mixbox.

I can see this being implemented in Affinity Photo, but for Vector color mixing, it's a long shot and unlikely. I'd love to have it in the pixel persona though. Thanks for sharing!

Would also like to see this implemented but in affinity photo.

Looking at the github, the code license is proprietary for commercial use, as this would be.

A free comparable solution might be using OkLab (with easy additions of OkHSL and OkHSV for color pickers too). That's a perceptually linear color space so functionally the same as what Mixbox is solving (mixing colors in a realistic way), though the math is a fair bit simpler since it's dealing with relatively simple colorspace translations instead of simulations of paint pigments. There are freely licensed code implementations of the algorithms in a fair few languages, too. It's gaining widestream support rather rapidly (Adobe themselves added it to Photoshop, yet not Illustrator yet), so it could be another marketable feature (tucked into the "Color Control" section on the homepage maybe).

 

There's already a feature request for adding OkLab, looks like:

Those colour mixing results look gorgeous. Would love to see it implemented into Affinity.

looking forward to see this function in future version of AD, AP, APub.

Hi!

My name is Ronald van Wijnen and I made my own implementation of the Kubelka-Munk Theory.

Is there any way to use this in Affinity Photo currently or do we have to wait for Affinity to add it?

Affinity has to add it if they want

That’s amazing!

I would really like to have support for this colour system in future.
Affinity, please!

Hello, I came across this video when researching digital colour mixing. Im not sure if Affinity has implemented this kind of tech in their apps. Anyway it lead me to this feed so I thought I would throw my hat into the ring and express my interest in this . Was interesting none the less.
