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 ...

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:
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.
The calculator uses the proprietary HP Nut processor produced in a bulk CMOS process and featured continuous memory, whereby the contents of memory are preserved while the calculator is turned off. [13] Though commonplace now, this was still notable in the early 1980s, and is the origin of the "C" in the model name.
The ColorChecker Classic chart is a rectangular card measuring about 11 by 8.25 inches (27.9 by 21.0 cm), or in its original incarnation about 13 by 9 inches (33 by 23 cm), an aspect ratio approximately the same as that of 35 mm film. [5]
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
The base-2 numeral system is a positional notation with a radix of 2.Each digit is referred to as a bit, or binary digit.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because ...
