"There is no blue without yellow and without orange." - Vincent Van Gogh
Back when I was a graphic designer at a lil small town newspaper I used to do all sorts of creative things all day long. Some of it was pretty much wasting time when you get down to it, but I like to look at it rather like building the creative mind instead of calling it a waste of time.
Anyway I used to frequent this website, Colourlovers all the time for color ideas. What you do is build a color palette of 5 colors. It is addicting! You can use photos to help make your palettes, or just pick colors. You can also then apply those colors to fun patterns. The coolest part though is you can download a file for photoshop or illustrator and thus import your colors into the color palette of the project you are working on. So awesome.
Click here to see colors and palettes I've designed. You should head over there and design some palettes of your own. It is fun!
