How to convert an RGB color to the closest matching 8-bit color?
The 8, 4, and 254 are the number of possible values in each color component. In your original 24-bit color, red, green, and blue can all have 256 possible values, so that is the divisor of the scaling equation. In the example 8-bit color, red and green are each 3 bits (8 possible values) and blue is 2 bits (4 possible values).

2011年5月12日 · I've color values coming in six bits, with two bits each for red, green and blue. So black would be represented as binary 000000, red 110000, blue 000011, yellow 111100 and so on.
converting images to indexed 2-bit grayscale BMP
2016年3月4日 · I need to convert images to 2-bit per pixel grayscale BMP format. The sample image has the following properties: Color Model: RGB Depth: 4 Is Indexed: 1 Dimension: 800x600 Size: 240,070 bytes (4 bits per pixel but only last 2 bits are used to identify the gray scales as 0/1/2/3 in decimal or 0000/0001/0010/0011 in binary, plus 70 bytes BMP ...
image - What does bit per color channel means? - Stack Overflow
2019年10月26日 · Bits per color channel, is the number of bits that are used for storing a color component of a single pixel. RGB color space has 3 channels: Red, Green and Blue. The "bits per color channel" (bpc) is the number of bits that are used for storing each component (e.g 8 bits for red, 8 bits for green, 8 bits for blue).
Do all 8 bit colors exist in 24 bit color space? If so how to map?
2014年8月27日 · With 8 bit color depth there are 256 colors. With 24 bit color depth there are 16,777,216 colors. Is there a direct mapping between every color in the 8 bit space to a color in the 24 bit space? I would think the answer to this question is yes, but the comments to this answer suggest the mapping is only an approximation.

java - How to get 8 bit Colors? - Stack Overflow
2014年12月4日 · 3 * 64 = 192 (Alpha) 0 * 64 = 0 (Red) 2 * 64 = 128 (Green) 1 * 64 = 64 (Blue) And put them back into a Color object. As you can see, the colors are different: some information about the color was lost in the process. This is called lossy compression.
