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.

16.7 million. 24 bit is also referred to "True Color".
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.
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).
A 32 bit per pixel bitmap will have 8 bits each for red green and blue, and 8 bits for alpha level. So 2^24 colors.

A 24-bit video adapter can display roughly 16 million different colors.

Oh, dude, a PNG image can technically contain up to 16.7 million colors thanks to its 24-bit color depth. That's like a whole rainbow on steroids! So, yeah, you can pretty much throw any color you want into a PNG image and it'll handle it like a champ.
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.
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.
Jpeg supports up to 24 bit RBG (2^24 colors).
A 32 bit per pixel bitmap will have 8 bits each for red green and blue, and 8 bits for alpha level. So 2^24 colors.
