Extreme Min Temp Tool: Color Ramp Suggestions

[hadinon]

Reverse the color ramp for occurrence maps (warm sites/low values = red, cold sites/high values = blue) Maybe remove green color in the Projected Change color ramp since green could be associated with good? (MEDIUM PRIORITY)

I added new color ramps for this tool. I think the Projected Change one is fine; it's basically the same as before but without the green.

For the Historical and Projected Occurrence displays, I basically reversed the color ramp, and I don't like how it looks. For one, in my mind, pink and red correspond to high values, but they are associated with low values here. Also, the color range from yellow → orange → red → pink is also used for the Projected Change map, but the order is reversed (from low to high instead of high to low).

I think I will probably re-do the Occurrence palette with non-conflicting colors. I'm thinking of maybe the USDA plant hardiness zone color ramp, from brown/beige → green (sorry, Eric) → blue → purple. That way, we also avoid having any red colors and it being misinterpreted as red = warm or red = high values.

I made the new changes to the Historical/Projected Occurrence palette. In case you didn't get to see the last version, here's the comparison.

Version A

Version B

I definitely prefer the second version, although I may remove some of the bluish-purple colors since I have a hard time telling them apart.

As of last Friday, the slightly updated color ramp is in place:

I personally like how this one looks, so unless you or the beta testers have any suggestions, this will probably be what we go with for this tool.
