Another Color Chart …

… this one for the sixth-generation (1979 to 1985) Rivieras. Colors not even close to fully calibrated. Click the image to expand somewhat.

 

 

Some notes:

 

1) Thin black horizontal lines indicate that the color formulation is the same, even when the name isn't the same. They also indicate when the exact same formulation came back after a few years and when a color carried over from the previous generation.

 

2) The number is the actual Buick paint number, while an asterisk indicates metallic. Even if the paint number didn't change, the formulation sometimes did, like Red Firemist from 1982 to 1983.

 

3) Colors are sorted by their Hue value. One of the many ways to describe a particular color is the HSB color space—Hue, Saturation, and Brightness. Also named as HSL (Hue, Saturation, and Lightness), HSB is a different way of measuring the RGB color space. The interest here is that it nicely separates hue from other color factors over 360 degrees, with the red in ROYGBIV starting at about 345 degrees.

 

HSB was initially conceived as a way to add color to black-and-white television transmissions without changing the signal that the black-and-white sets were receiving. It has been around for quite a while—French engineer Georges Valensi invented it in 1938, pre-dating the first consumer color televisions by 16 years.
