First of all thanks for the comments and info.
I'm actually not doing the color interpolation myself. I'm using chroma.js[1] for the most part.
You can actually change the interpolation mode on the bottom below the color boxes. The default is LCH because I think it looks the best most of the time, but you can use LAB if you prefer that.
