In addition to using these color combinations, there are also some rules and suggestions that are easy to follow. If you have a good black and white interface and apply color to it in a constructive manner, you will obtain a better interface. Murch's Rules Avoid the simultaneous display of highly saturated, spectrally extreme colors. Pure BLUE should be avoided for text, thin lines, and small shapes. Older operators need higher brightness levels to distinguish colors.
Colors change in appearance as the ambient light level changes.
The magnitude of a detectable change in color varies across the spectrum. It is difficult to focus upon edges created by color alone. Opposit colors go well together. One of the most important elements in using color effectively is knowing the user, the user's environment, and the task the user is performing. This is just as important for the integration of color as it is for any other part of interface design.
