10) Color Scheme Generator 2

Color Scheme Generator 2 creates different types of color schemes based on one color, which uses algorithms to find other colors that supplement the base color using the color scheme of your choice such as monochromatic, contrast, triad, tetrad and analogic. The help page explains the process and provides other information including downloading the application.

Not only do you find different color schemes with Color Scheme Generator 2, but also you can see how they look to people with various types of color blindness. Each type of color blindness is accompanied with population information -- how much of the population has the condition. Just pick one condition and the color scheme changes.

The application immediately displays variations of your selected color scheme. Choices include pastel, dark pastel, light pastel, contrast and pale. You can enter RGB values (six-digit hexadecimal code). You can save the URL of your scheme for later use.
