  Proof of concept for a color mixer interface

Really cool!

So it looks like you're combining Delauny triangulation for the points with linear interpolation along the created triangles using Barycentric coordinates? Did I get that right? Pretty elegant solution (not to mention all the other little details that went into designing the interface).

It still looks a bit strange along the edges sometimes, and glancing at the source code it seems like you're mixing in linear RGB[0] so it's not that. I guess that just means that I'm looking at a saddle point in the color space?

(this made me wonder how smoothing functions would work for triangle meshes (that aren't secretly quads split into two triangles), and a quick search suggests that could be quite a deep rabbit hole to fall into)
