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.
For a digital photo, bit depth is the number of colors that can be shown in the image. Because the bits can only indicate one of 2 possible states (0 or 1), the number of colors can only be powers of 2. Some examples of bit depths (and the calculation of the decimal number for those of you who know exponents) for image files are: 2-bit (2^2 = 4 colors), 4-bit (2^4=16 colors), 8-bit (2^8=256 colors), 16-bit (2^16=65,536 colors), and 24-bit (2^24=16,777,216 colors).
BMP (Bitmap) format supports a wide range of colors depending on the bit depth. It can represent 1-bit images (black and white), 4-bit images (up to 16 colors), 8-bit images (up to 256 colors), and higher bit depths like 24-bit, which supports over 16 million colors (approximately 16,777,216 colors). Additionally, there are even higher bit depths, such as 32-bit BMP files, which include an alpha channel for transparency but still represent the same range of colors as 24-bit.
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.
The BMP (Bitmap) format supports a wide range of colors, depending on its color depth. It can represent images in various color depths, including 1, 4, 8, 16, 24, and 32 bits per pixel. At 24 bits per pixel, BMP can display approximately 16.7 million colors, while 1-bit BMP supports just two colors (black and white).
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.

One bit is 2 possible colors, black, 8bit has a possible of 256
Graphics are also often described by the number of bits used to represent each dot. A 1-bit image is monochrome; an 8-bit image supports 256 colors or grayscales; and a 24- or 32-bit graphic supports true color.
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.

GIF format supports up to 8 bits per pixel, allowing a single image to reference a palette of up to 256 distinct colors chosen from the 24-bit RGB color space.JPEG files embed an ICC color profile (color space). Commonly used color profiles include sRGB and Adobe RGB which are often 24 bit (16.7 million colors). 255 255*255*255
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.
The 32-bit color offered by many current operating systems is actually 24-bits of color with 8-bits allocated to an alpha channel or data. This results in a color depth of 16,777,216 different colors. It is said that the human eye can only distinguish between 10 million different colors.
A 200x100 image with an 8-bit color depth means each pixel is represented by 1 byte. To calculate the total size, you multiply the width by the height and then by the number of bytes per pixel: 200 pixels * 100 pixels * 1 byte/pixel = 20,000 bytes. Therefore, the image size is 20,000 bytes.
This can vary wildly based on image format and other factors. For example, jpeg images can have smaller sizes (though lower quality) depending on how compressed they are. In the case of bitmaps, the amount of pixels that can fit into 100KB depends on its bit depth. A 1-bit 100K bitmap can fit 819,200 pixels. The 8-bit, 16-bit, 24-bit, and 32-bit bitmaps can fit 102,400, 51,200, 34,133, and 25,600 pixels, respectively. The general formula for how many pixels fit in an image of a certain size is as follows, for a bitmap: Pixels = [Size (in KB)] / [Bit Depth] x 8,192.
RGB-24 uses 1 byte for Red, Green and Blue respectively.256x256x256 or 2^24 different colorsRGB-32 uses 1 byte for Red, Green, Blue and Transparency/Alpha respectively. The number of possible colors is the same as RGB-24 since transparency does only specify how to over-impose the image and does not define a color property by itself.
