Climate Key
The climate map uses the Köppen climate classification system. You can read more about it here. Climate groups are classified using a two or three letter name, and some have common names.
Every color represents a different (or a few different) climate group. Each climate name has a Wikipedia link to that climate's Wikipedia page.

A or Tropical Climates
Dark blue: Af or tropical rainforest
Blue: Am or tropical monsoon
Light blue: As/Aw or tropical savanna
B or Dry Climates
Red: BWh or hot desert
Pink: BWk or cold desert
Orange: BSh or hot steppe
Light orange: BSk or cold steppe
C or Temperate Climates
Yellow: Csa/Csb/Csc or Mediterranean
Pale green: Cwa/Cfa or humid subtropical
Bright green: Cfb/Cfc/Cwb/Cwc or oceanic
D or Continental Climates
Sky blue: Dsa/Dsb/Dwa/Dwb/Dfa/Dfb or humid continental
Dark green: Dsc/Dsd/Dwc/Dwd/Dfc/Dfd or subarctic
E or Polar Climates
Light gray: ET or tundra
Dark gray: EF or ice cap

FAQ: Why didn't you include every climate type as its own color?
This map is based off of real-life weather phenomena. Using the latitude on the side of the map, I determined wind patterns and ocean currents. Then, using that, I determined climate based off of local temperature and precipitation. This is why I won't let you change your climate without changing location, even if you ask nicely.
However, in the real world, it's much easier to make such a map, as you simply take weather measurements from around the world. This allows you to define many more climate types that have much smaller variation. I simply cannot determine enough variables to figure out how every single type would be placed, so I just picked the major ones and lumped the smaller ones in.
