English: Color star using the RGB color model Own work based on: Color star-en.svg and An existing RYB image.This model uses names for hues that are uncommon in color theory and do not reflect standard hue naming.
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
As such, color spaces are an essential tool for color reproduction in print, photography, computer monitors, and television. The most well-known color models are RGB, CMYK, YUV, HSL, and HSV. Because the perception of color is an important aspect of human life, different colors have been associated with emotions, activity, and nationality.
The first versions of Mosaic and Netscape Navigator used the X11 colors as the basis for the web colors list, as both were originally X applications. The W3C specifications SVG and CSS level 3 module Color eventually adopted the X11 list with some changes. [7]
In optics, violet is a spectral color: It refers to the color of any different single wavelength of light on the short wavelength end of the visible spectrum (between approximately 380 and 435 nanometers), [16] [17] whereas purple is the color of various combinations of red, blue and violet light, [5] [6] some of which some humans perceive as ...
YCbCr is sometimes abbreviated to YCC.Typically the terms Y′CbCr, YCbCr, YPbPr and YUV are used interchangeably, leading to some confusion. The main difference is that YPbPr is used with analog images and YCbCr with digital images, leading to different scaling values for U max and V max (in YCbCr both are ) when converting to/from YUV.
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] The current version of the NCS was developed by the Swedish Colour Centre Foundation, from 1964 onwards.
The "attribute of a visual sensation according to which the perceived color of an area appears to be more or less chromatic". [8] The HSL and HSV color spaces are more intuitive translations of the RGB color space, because they provide a single hue number. However, their luminance variation does not match the way humans perceive color.
