Sometimes a task to design a simple web page arises. First step is designing layout of site. Second step is designing color palette. For me personally it is always a most complicated step which can be accomplished with an external help only. Lately I found a beautiful helper – http://colorschemedesigner.com/.
It simply does everything. You just need to choose a color and color layout type. The rest will be done by software. It will offer you to adjust layout, to see sample designs on HTML page, to export designs in several formats and make you coffee. I recommend.
