Old gold is a dark yellow, which varies from heavy olive or olive brown to deep or strong yellow. The widely accepted color old gold is on the darker rather than the lighter side of this range. The first recorded use of old gold as a color name in English was in the early 19th century (exact year uncertain). [6]
This standard has four variants for each non-monochromatic color: clear (50% transparent), dark, light and the default. Wherever possible, the values are the same as in the W3C adaptation of the X11 list, except for Turquoise which is instead of . Missing variant values have been added systematically. Buff and Mustard are completely new color ...
The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.
On a typical standard 2.2-gamma CRT display, an input intensity RGB value of (0.5, 0.5, 0.5) only outputs about 22% of full brightness (1.0, 1.0, 1.0), instead of 50%. [19] To obtain the correct response, a gamma correction is used in encoding the image data, and possibly further corrections as part of the color calibration process of the device.
RGB values are usually given in the 0–255 range; if they are in the 0–1 range, the values are multiplied by 255 before conversion. This number divided by sixteen (integer division; ignoring any remainder) gives the first hexadecimal digit (between 0 and F, where the letters A to F represent the numbers 10 to 15. See hexadecimal for more ...
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.

Colors are an important part of visual arts, fashion, interior design, and many other fields and disciplines. The following is a list of colors. A number of the color swatches below are taken from domain-specific naming schemes such as X11 or HTML4. RGB values are given for each swatch ...
Ternary plot of different colors of Ag–Au–Cu alloys [1]. Colored gold is the name given to any gold that has been treated using techniques to change its natural color. Pure gold is slightly reddish yellow in color, [2] but colored gold can come in a variety of different colors by alloying it with different elements.
