Color combos
Some color combinations strike a chord with me. Of course, as taught in my color theory classes in art school, all colors evoke some type of mood or emotion. Light blues often convey a feeling of calm. Yellows and oranges are cheerful and bright. Reds gain attention quickly - and depending on the specific hue of that red can either create feelings of anger or strength.
However, while single colors do have specific emotions tied to them, I think so do color combinations. Have you ever looked at something and thought "Wow, I love those colors!!!"? I do all the time. I am so inspired by color. I've recently seen a couple of layouts that I have fallen in love with that use this color combo - a deep rich red and a robin's egg/turqouise blue-ish color. It's an unlikely combination and maybe that's why I love it so much.
What's your favorite color combination?
