Color schemes can be selected for different classification types (sequential, diverging, and qualitative) and for any number of classes (ranging from three to twelve). The website provides the numeric values for colors in RGB, CMYK, and HEX, and provides options to show only colors that are colorblind safe, photocopy-able, and print friendly. The graphic below is a screenshot of the website which portrays the user-friendly interface and the numerous options for color schemes and data representation.
