USE OF CHROMATICITY DIAGRAM

When we plot the normalized amounts x and y for colors within the color spectrum, we obtain the tongue-shaped curve. This curve is named the CIE chromaticity diagram.

The chromaticity diagram is beneficial for the following:

1. Comparing colors gamut’s for various sets of primaries.
2. Identify the complementary colors.
3. Determining dominant wavelength and purity of a given color
