I found this great tool for web designers whilst on my CSS learning binge. It’s a color scheme designer. Just punch in a hexadecimal color figure and it will tell you the complimentary and contrasting colors. It will even let you preview what the scheme will look like to people with various types of colorblindness. The only problem is that I can’t get it to suggest the colors I chose for my own website. 😐
I’ll just link it here so I can find it easily in the future.
