A bit represents two colors or states, typically represented as 0 and 1. In digital systems, these can correspond to different colors or signals, but fundamentally, a single bit can only convey two distinct values. When multiple bits are combined, they can represent a broader range of colors; for example, 8 bits can represent 256 different colors.
A 24-bit color depth can represent 2^24 colors, which equals 16,777,216 distinct colors. This is achieved by using 8 bits for each of the three primary colors: red, green, and blue (RGB). Each color channel can have values ranging from 0 to 255, allowing for a wide spectrum of colors.
A 1-bit image can represent two colors, typically black and white. This is because each pixel in a 1-bit image can only have one of two possible values, often denoted as 0 and 1. Therefore, the image can display only these two colors without any gradients or shades.

To represent 256 colors, you need a minimum of 8 bits. This is because 2^8 equals 256, meaning each of the 256 possible values can be represented by an 8-bit binary number. Each bit can be either 0 or 1, allowing for a total of 256 unique combinations.
The amount of information stored in a dot (pixel) and expressed in bits is called "bit depth." Bit depth indicates how many bits are used to represent the color of each pixel in an image, determining the range of colors that can be displayed. For example, an 8-bit depth allows for 256 different colors, while a 24-bit depth can represent over 16 million colors.
A 24-bit color depth can represent 2^24 colors, which equals 16,777,216 distinct colors. This is achieved by using 8 bits for each of the three primary colors: red, green, and blue (RGB). Each color channel can have values ranging from 0 to 255, allowing for a wide spectrum of colors.
A 1-bit image can represent two colors, typically black and white. This is because each pixel in a 1-bit image can only have one of two possible values, often denoted as 0 and 1. Therefore, the image can display only these two colors without any gradients or shades.
The main difference between 8-bit, 10-bit, and 12-bit color depths is the number of colors they can represent. 8-bit can display 256 colors, 10-bit can display 1,024 colors, and 12-bit can display 4,096 colors. Higher bit depths allow for more accurate and detailed color representation, resulting in smoother gradients and reduced banding in images and videos.

Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.

One bit is 2 possible colors, black, 8bit has a possible of 256
A 24-bit video adapter can display roughly 16 million different colors.
An 8 bit colour display can show 256 colours.
You are actually asking how many colors are possible in 8 bit per channel. 8 bit per channel means 256 colors, 1 bit= 2 colors, 2 bits= 4 colors, 3 bits= 8 colors, 4 bits= 16... 8bits= 256 colors. Since we have 3 channels in RGB color mode: Red, Green and Blue that means that we have 3x8= 24 bits per pixel in an image. 3x8 also means 256x256x256 colors possible. Number of possible colors in 8 bit per channel or 24 bits per pixel image is 256x256x256 colors or in particular exact number of possible colors is 16777216.
