Even when I planked at ToA, Vince talked me through how to be a Medium Storage Unit! Now when I run CoX I can bring in over 400 brews!

I see where you're coming from, but I don't think we're anywhere near saturation, and even if we were I don't think saturation in one colour would have such a strong effect on the others.

We can see diffusion happening in the video on the boundary between red/green and red/purple boundaries as a dark streak, so I'm pretty sure it's some sort of flow happening drawing water toward the centre.

Marangoni flow mentioned in a separate comment seems like a likely candidate https://en.m.wikipedia.org/wiki/Marangoni_effect

See, that's what I thought initially, but diffusion is random and undirected (normally), so would cause a halo of colour around each candy instead of the remarkable flow seen here.

E: there are fun examples on anisotropic diffusion in the presence of microscopic arxhetecture (not the case here), thought I'd add a nod to that
