I didn't notice much difference between stretched 1x1 pixel sprite and tiled bg.
Regarding your method of changing background color, how would you automate it to go well with conditions? With animation frames it's very easy to always set the correct frame if you put all the frames in right order, like if each biome has 4 seasons then biome 0 has frames 0-3 and if you want to set the color to biome 0 season 3 then you set the animation frame = biome_number*4 + season_number, so you need to only use one condition that always sets the correct image color.
It's very similar
Name the files numbers like 0.png, 1.png, 2.png, etc
Then just do Load Image from URL biome_number*4 + season_number & ".png"
