Best way to create custom color palettes for visualization

Colorbrewer is awesome, but quite restrictive. After browsing the web for some time, here's the best too I found, with tools to create very nice-looking, yet usable and informative custom color scales in any aesthetics you want. It's called the "chroma scale helper":

Here's the description of how it works (it's very clever, and worth the read on its own, even if you never use the actual scale helper"

Here's a table of color names it uses (you may have to browse for the color you like, but it's very doable)
