One starts with a white substrate (canvas, page, etc.), and uses ink to subtract color from white to create an image. CMYK stores ink values for cyan, magenta, yellow and black. There are many CMYK colorspaces for different sets of inks, substrates, and press characteristics (which change the dot gain or transfer function for each ink and thus ...
Each color code listed is a shorthand for the RGB value. For example, code 609 is equivalent to RGB code 102-0-153 or HEX code #660099. Safest web colors. Designers were encouraged [by whom?] to stick to these 216 "web-safe" colors in their websites because there were a lot of 8-bit color displays when the 216-color palette was developed.
The NCS color model is based on the three pairs of elementary colors ( white – black, green – red, and yellow – blue ), as defined by color opponency. The Natural Color System ( NCS) is a proprietary perceptual color model. It is based on the color opponency hypothesis of color vision, first proposed by German physiologist Ewald Hering. [1]
In color theory, a shade is a pure color mixed with black. It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a "shade of black" is always a pure black itself and a "tint of black" would be a neutral gray. In practice, many off-black colors possess a hue and a colorfulness (also called saturation).
Any color space based on such a 24-bit RGB model is thus limited to a range of 256×256×256 ≈ 16.7 million colors. Some implementations use 16 bits per component for 48 bits total, resulting in the same gamut with a larger number of distinct colors. This is especially important when working with wide-gamut color spaces (where most of the ...
Generally, the number of colors in a qualitative color scheme is equal to the number of possible values for the categorical variable, where each value is encoded to one color. However, the number of total colors can be decreased by encoding each value with multiple colors, as in the 25-pair color code, which encodes 25 values using only 10 ...

RAL Design System+ In the RAL Design System Plus, there are groups of colours every 10° of hue and additionally at 75°, 85° and 95°. Possible lightness values are 15% through 90% in steps of 5% for monochromatic shades of grey (i.e. C = 0%) and 20% through 90% in steps of 10% and additionally 85% and 93%.
