RGBA stands for red green blue alpha. While it is sometimes described as a color space , it is actually a three-channel RGB color model supplemented with a fourth alpha channel . Alpha indicates how opaque each pixel is and allows an image to be combined over others using alpha compositing , with transparent areas and anti-aliasing of the edges ...
Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is ...
A remainder of nine gives the hexadecimal number C9. This process is repeated for each of the three color values. Conversion between number bases is a common feature of calculators, including both hand-held models and the software calculators bundled with most modern operating systems. Web-based tools specifically for converting color values ...
Systems with a 12-bit RGB palette use 4 bits for each of the red, green, and blue color components. This results in a (2 4) 3 = 16 3 = 4096-color palette. 12-bit color can be represented with three hexadecimal digits, also known as shorthand hexadecimal form, which is commonly used in web design. The palette is as follows:
The sRGB standard defines the chromaticities of the red, green, and blue primaries, the colors where one of the three channels is nonzero and the other two are zero.The gamut of chromaticities that can be represented in sRGB is the color triangle defined by these primaries, which are set such that the range of colors inside the triangle is well within the range of colors visible to a human ...
RGBA is RGB with an additional channel, alpha, to indicate transparency. Common color spaces based on the RGB model include sRGB , Adobe RGB , ProPhoto RGB , scRGB , and CIE RGB . CMYK uses subtractive color mixing used in the printing process, because it describes what kind of inks need to be applied so the light reflected from the substrate ...
1931 CIE chromaticity diagram showing some RGB color spaces as defined by their chromaticity triangles. RGB color spaces is a category of additive colorimetric color spaces [1] specifying part of its absolute color space definition using the RGB color model.
Because of the low amount of memory and resultant higher speeds of 8-bit color images, 8-bit color was a common ground among computer graphics development until more memory and higher CPU speeds became readily available to consumers.
