Ok, wow - that was an uphill struggle! I've remade temperature and precipitation maps, then managed to install Python and even got the script to run (after a lot of Google Fu) - but then saw I have to change the colors. I guess new precipitation maps are in order.

At least I made these two new temp maps based on your feedback, and since I'd used masks and full color fields they were easy to modify so they would work.

New precipitation maps will have to wait - I'll make them to follow these color values:
(Heaviest) 135, 0, 180) :300
130, 60, 200) :170
105, 70, 200) :105
60, 60, 180) :55
70, 95, 150) :30
55, 85, 100) :15
35, 50, 50) :7.5
(Driest) 20, 20, 20) :2.5
Ocean 107, 165, 210) :O
