CIE Diagram

This is an interactive CIE 1931 chromaticity diagram that can be used by professionals in color science and technology, color related product design or anyone with an interest in color space. The diagram is drawn dynamically with the best accuracy that the display device can support. The tool allows the user to see the CIE xyz coordinates and RGB values of any selected point on the CIE chromaticity diagram. It also shows the area of the diagram that can be rendered by a standard display device based on RGB mixing and monochromatic (single wavelength) light of any selected wavelength.
