Truer Color Chart

To describe the colors of ancient gems, I create this easy to understand color chart.

These colors optimize the true colors as close as possible, given the limitations of digital screens.

Red, Orange, Yellow, Green, Blue, Purple.

The Color Chart above illustrates the primary colors according to pigments for paints, dyes, and other materials - Red, Yellow, Blue.

I determine these colors carefully.

Most online charts determine their colors mechanically. Example: RGB digital “Orange” equals “75% Red, 25% Green”. But such digital Orange is quite reddish, and not true orange. By contrast, the Color Chart Orange strives to display the pure orange.

The Color Chart determines each color according to the way a person experiences the color. As pure as possible.

Of course, each digital screen displays the Color Chart slightly differently (unless calibrating), but its colors should be close to the truer color that the screen can display.

Current technology limits the range of colors that digital screens can display. Therefore, the Color Chart tries to work with the typical limitations to optimize for truer colors.

• The digital Yellow of the screen is true enough. It is the mix of the light from red and green pixels. The yellow may display especially true if the screen is “RGBy” with extra yellow pixels to enhance yellow.

• The digital Red is orangish. It can be virtually identical to the orange-red color of the pigment, vermilion. So the Color Chart Red displays the truest red possible (reducing the orange by adding digital Blue to neutralize the hint of digital yellow). Within the brilliant hues of red, relatively speaking, the Color Chart Red finds the threshhold between the orangish salmon-pink and the purplish magenta. It never quite hits the true red, but it does find the “gray” compromise, whose dusky red is neither so orange nor so purple.

• Similarly, the digital Green is very yellowish. Therefore, the Color Chart Green finds the “gray” compromise at the threshhold between the yellowish green and bluish green. The resulting color is very pale, but it is the truest green that the digital screen can do.

• The digital Blue is actually on the threshhold of purple-blue. It is a brilliant deep color, but it has a slight hint of red. By contrast, the Color Chart Blue is a solid blue between green-blue and purple-blue.

• These colors − Yellow, Red, Green, and Blue − then anchor the other colors, that space equadistant between them − not mechanically, but subjectively as a mind perceives them. Example, the Color Chart Purple approximates the visual experience in between Red and Blue, being at the threshhold in purple that is least Reddish and least Bluish, and so on for the other colors.

Enjoy the colors.
