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.
Mode 13h is something of a curiosity, because the VGA is a planar device from a hardware perspective, and not suited to chunky graphics operation. The VGA has 256 KiB of video memory consisting of 4 banks of 64 KiB, known as planes (or 'maps' in IBM's documentation).
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.
English: Default VGA palette (256 colors) serving for 4 different needs in a single colour table [1] The first 16 colours are encoded exactly as with all 16 colour modes (0Dh/0Eh/10h/12h) which in turn use the same 4 bit encoding as the colour attributes of all text modes (*1)
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...

Since an 8-bit color display can not display two images with different color maps at the same time, it is usually impossible to display two different 8-bit images on the same such display at the same time. In practice, in order to avoid this problem, most images do not use the full range of 256 colors.
