Here is an update to my avatar. I have reduced colours all the way down to 19 from about 64.
Then I made a yellow version for the March colour thing, which has 16, but it'll eventually cycle back to normal.
Then I made a blue version, which has 15 colours.
Then I made a green version, which has 16 colours.
Then I made this red version, which has 20 colours.
I'm thinking yellow will be to represent Autumn.
I'm thinking blue is for Winter, since the sky can be seen.
I'm thinking green is for Spring.
And I'm thinking red is for Summer, with ripe fruit in abundance.
