CIE Diagram is an interactive tool to explore CIE 1931 chromaticity diagram.
Tap any point in the horseshoe-shaped gamut to place a location indicator on the diagram and see its corresponding xyz coordinates and RGB values. The circle above these values shows the color. Tap any point outside the gamut to remove the location indicator.
Select "No Added White" (Windows Store App) or "No White" (Windows Phone App) to display only the area of the diagram that can be rendered by a standard display device based on RGB mixing.
Select "Single λ" to display the point corresponding to monochromatic light of any selected wavelength. Move the wavelength slider, click "+" or "-" button to select the wavelength.
