When developing sites (or GUI) there are problem on selecting color schema (like making header - red, footer - blue, sidebar - yellow, text - black, zebra - white/green).
There are color schema exchange sites, freeware tools and sites. Like http://colorschemedesigner.com/
But search on Github/SourceForge/FreeCode didn't give any OpenSource tools to study used algorithms and techniques for picking color schema.
My goal to build such tools (I think simply in JS/HTML5) but I don't understand how to select color combination so it look acceptable for people.
PS. I don't ask this question at http://ux.stackexchange.com as its rules state that algorithms are offtopic at UX.
