kuler, an interesting site for color combination ideas.
As suggested by Caroline Andreolle, aspiring interior designer, who said:
But especially with color, it’s super hard to remember. Was that the exact blue I saw? What kind of brown was that? I’m a visual person, but I’m not that visual. So I used Evernote to remember decors, painting tips, color combination’s, find palettes of colors to make sure you wouldn’t get a heart attack looking at that red next to that purple. In short, Evernote’s my personal interior decorator.
