This list of RGB palettes includes generic repertoires of colors (color palettes) to produce RGB color pictures.

Regular RGB palettes[edit | edit source]

Here are grouped those full RGB hardware palettes that have the same number of binary levels (i.e., the same number of bits) for every red, green and blue components using the full RGB color model.

9-bit RGB[edit | edit source]

Systems with a 9-bit RGB palette use 3 bits for each of the red, green, and blue color components. This results in a (23)3 = 83 = 512-color palette.

9-bit RGB systems include the following:

12-bit RGB[edit | edit source]

Systems with a 12-bit RGB palette use 4 bits for each of the red, green, and blue color components. This results in a (24)3 = 163 = 4096-color palette.

12-bit RGB systems include the following:

15-bit RGB[edit | edit source]

Systems with a 15-bit RGB palette use 5 bits for each of the red, green, and blue color components. This results in a (25)3 = 323 = 32,768-color palette (commonly known as Highcolor).

15-bit RGB systems include:

18-bit RGB[edit | edit source]

Systems with an 18-bit RGB palette use 6 bits for each of the red, green, and blue color components. This results in a (26)3 = 643 = 262,144-color palette.

18-bit RGB systems include the following:

24-bit RGB[edit | edit source]

Often known as truecolor and millions of colors, 24-bit color is the highest color depth normally used, and is available on most modern display systems and software. Its color palette contains (28)3 = 2563 = 16,777,216 colors.

24-bit RGB systems include:

Non-regular RGB palettes[edit | edit source]

These also are full RGB palette repertories, but either they do not have the same number of levels for every red, green and blue components, or they are bit levels based.

16-bit RGB[edit | edit source]

Most modern systems support 16-bit color. It is sometimes referred to as Highcolor (along with the 15-bit RGB), medium color or thousands of colors. It utilizes a color palette of 32×64×32 = 65,536 colors. Usually, there are 5 bits allocated for the red and blue color components (32 levels each) and 6 bits for the green component (64 levels), due to the greater sensitivity of the normal human eye to this color.

16-bit RGB systems include the following:

It must be noticed that not all systems using 16-bit color depth employ the 16-bit, 32-64-32 level RGB palette. Platforms like the Neo Geo videogame console employ the 15-bit RGB palette (5 bits are used for red, green, and blue), but the last bit specifies a less significant intensity or luminance.
