A system of subtractive color does not have a simple chromaticity gamut analogous to the RGB color triangle, but a gamut that must be described in three dimensions. Source: Internet
Chromatic-strung harps Some harps, rather than using pedal or lever devices, achieve chromaticity by simply adding additional strings to cover the notes outside their diatonic home scale. Source: Internet
By empirical means he determined that the difference in sensation, which he termed ΔE for a "discriminatory step between colors…Empfindung" (German for sensation) was proportional to the distance of the colors on the chromaticity diagram. Source: Internet
As noted above and seen in the accompanying photograph, the chromaticity of birefringence typically creates colored patterns when viewed in between two polarizers. Source: Internet
For different wavelength regions, or for higher precision in characterizing a system's chromaticity (such as in the design of apochromats ), the full dispersion relation (refractive index as a function of wavelength) is used. Source: Internet
