Working on Adobe Kuler has been quite an experience for me. Though i am a person who loves color, creating new themes was something i thought need major skills to come up with combinations!
Though i have done Color Theory in grad school, i still think you need to be a pro with colors to come up with breakthrough combinations with restrictions/constraints haunting your head.
So i played around on it for a while, didnt make any combinations public for obvious reasons.
Couple of months later i have edited and made them available publicly after checking out major funny combinations people have posted!
Hey you need a learning curve right? so from 6 combinations to 18 to 24 combos, 4 have been downloaded at least once, 1 twice, another 1 thrice and 1 has been downloaded five times….
hmm….not bad for a start i think

So have you tried it yet?
