C.I.E. Chromaticity Diagram

Please visit Sencore as a gesture of gratitude for allowing the use of their industry standard C.I.E. Chromaticity Chart.

Here is a very detailed dissertation on the subject of chromaticity, along with software for generating multiple version of the chart.

Chromaticity is commonly defined as the quality of color characterized by its dominant or complementary wavelength and purity taken together. This chromaticity chart plots the human tristimulus color space according to:

    x = X/(X + Y + Z),
    y = Y/(X + Y + Z).

Colors along the periphery of the "horseshoe" plot (spectral locus) are pure, monochromatic, saturated colors. Less saturated colors approach the center becomes (i.e. it becomes whitish or grayish). The straight line across the bottom is called the "non-spectral line of purples."

Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
