In Shape Maps, the color palette seems too subtle. #671

Can we get a wider range pallet to make the differences more visable?

Red to green is a classic - other thoughts?

Here's our current pastel gradient that we use for charts (the non-pastel version hurts my eyes):

I like what you did with the contrast! If we go the red/green route, I think I've read that you can use magenta + green to be slightly friendlier to red-green color blindness, if we go down that path probably worth a little research there.

I've done a TON of research into this, while working on the Looker color palettes. We need to keep things single-color, starting lighter, and ending darker - until we get some smarts put in for divergent color setups (negative-to-zero-to-positive). Multiple colors don't work for the regular case because you can't tell what the colors mean. :-)

colors looker palettes...

For now we landed on light blue to dark blue. The larger issue of reworking our visualizations to be more friendly remains open for now.
