Starting March 1, In the spirit of a 'non-competitive-free-to-participate-in-almost-wannabe-fad event', Metaru wants you to wear different colored versions of your avatar, for every week in March.
You can either upload a new version of your avatar, edit your current avatar's preview to avoid uploading another one (if it's yours of course) or find an avatar in the gallery that fits the mood of your character.
the dates for each color scheme are as follows:
March 1-7: Yellow
March 8-14: Blue
March 15-21: Green
March 22~31: Red
