so ive been doing some tests using the temperature and precipitation maps azelor made for the koppen climate guide and applying mbartelsm's biome guide to it. specifically i've been testing the statement in mbartelsm's guide which states "Take your precipitation and temperature maps and recolor them according to the key below. It doesn't matter if you paint summer green or blue, as long as it's not the same as winter otherwise we will get some odd overlap because color scales are linear and the scales used for the holdrige life zones are logarithmic." specifically where it says that it does not matter which color you make your seasonal precipitation or temperature maps so long as they arnt the same color (ie they cant both be blue or cant both be green). i found this not to be true though. when merged a blue summer green winter map does not look like a green summer blue winter map whether it is temperature or precipitation. however i was willing to keep going and see if the differences in the maps ever worked themselves out. so when i reached the 2nd stage i found that the temperature maps do work out to be the same in the end except the summer blue winter green temperature map which has blue hues that dont exist in the guide. everything else though looks the same when its converted over to red. this is not the case for precipitation though. all of the hues on the precipitation maps are covered by the guide but the final results of the precipitation maps are slightly different in some areas if you use winter green summer blue as oppose to winter blue summer green. because i couldn't use the summer blue winter green temperature map i applied the summer green winter temperature map to the 2 precipitation maps and rendered biomes from them. the pattern is still fairly similar but there are slight differences the biome map with the precipitation winter blue and summer green gave me a slightly more arid map than where the precipitation map was winter green and summer blue

in the attachments below you see the first biome map coming from a winter green and summer blue precipitation map and the one below it a winter blue and summer green precipitation map
