Hi Chris, I'm going to be slow to respond with how busy work is for the next two months. But don't worry, I'm committed. My github name is mikejwaters.
How hard would it be to implement a function that interpolates the RGB value from a look up table of colors? In the future, users could upload their own 'custom_colormap.csv' maybe? I'm brainstorming, but I must admit I'm not much of a JS programmer. Mostly Python for me.
Stylistically, I think a diverging colormaps make the most sense since we think of the bed plane as a reference level that we deviate from.
Here's an example that should be great for colorblindness.
