Profile randomly changing colours?

[KidBeano]

It seems that my profile keeps changing the colour scheme to seemingly random (and sometimes glaring) colours. I know I'm not doing anything to change it, and no other suspicious activity seems to be going on on my account. So, is this a known issue, or am I just missing something?

I had this problem too, and I just had to manually reset the colors so I could read my profile page...

There was a problem earlier which caused all the uncustomized profiles to go all blue. I've reset the the default theme to the grayscale-ish theme you see now.
