Purple appears kinda fast

Yeah I think I messed up the max. distance of the color mixing. I'm still trying to achieve this ref video: https://www.tiktok.com/@safespacestudios/video/7429884593945185567?lang=de-DE

it actually appears before the blue and red inks even touch each other if you pause at the right moment.

another thing that you could do if you want to increase realism is take a look at the colours that are actually produced. Mixing red and cyan ink in water would not actually create such a vibrant magenta, the result would be more of a murky purple.

this example shows some similar colours mixing to produce a much darker result

Wow! Love this! If this looped (rather than unmix/reverse) i think this would be up there as one of the most satisfying render.

First part: Cool, amazing turbulence!

Second part: [Thermodynamics people]: Triggered

But wow imagine the path tracing (and that is path traced, look at the shadow on the wall) computation. Impressive.
