24, or 16. Two of these are usually black and white, if you consider them colors. Computers usually do. 16-color video cards were common back in the 1980s, when computers were much smaller and slower than now.

How many colors are in 24 bit color image?
16,772,216 Colors
How many colors are available in a 24 bit color scheme?
16.7 million. 24 bit is also referred to "True Color".
How many colors are available with a 16-bit color depth?
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).
How many different colors is a 16-bit image capable of representing?
65,536 colors
How many colors does bmp contain?
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.

How many colors are generated in 64 bit color system?
32
How many colors are available in a 24 bit color scheme?
16.7 million. 24 bit is also referred to "True Color".
How many colors can a 32-bit computer display?
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.
If the display adapter is set to 8-bit color how many colors can it show?
An 8 bit colour display can show 256 colours.
How are GIFs made?
A gif or Graphics Interchange Format file can be made with any of a great number of image manipulation programs. The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to 256 distinct colors. The colors are chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.
7 How many colors can you have in a GIF image?
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

What is color depth in computer graphics?
Color DepthColor "depth" is defined by the number of bits per pixel that can be displayed on a computer screen. Data is stored in bits. Each bit represents two colors because it has a value of 0 or 1. The more bits per pixel, the more colors that can be displayed. Examples of color depth are shown in the following table:Color Depth1 bit color4 bit color8 bit color24 bit color No. of Colors21625616,777,216 Color ModeIndexed ColorIndexed ColorIndexed ColorTrue Color PaletteYesYesYesNoDetermining Color DepthSince each bit represents 2 colors, it is easy to work out the number of colors for the various color depths. The number of possible colors would be 2 to the power of the number of bits per pixel:A color depth of 4 bits would be 2 times itself 4 times:2 x 2 x 2 x 2 = 16 colorsA color depth of of 8 bits would be 2 times itself 8 times:2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 256 colors.A color depth of of 24 bits would be 2 times itself 24 times:2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 16,777,216 colorsTrue ColorImages are known as "True Color" where each pixel is defined in terms of its actual RGB or CMYK values. Every pixel in a a true color image has 256 possible values for each of it's red, green or blue components (in the RGB model) or cyan, magenta, yellow and black (in the CMYK model). Because there are 256 possible values for each RGB or CMYK component, then RGB true color would have a 24-bit color depth and CMYK true color would have a 32-bit color depth. There are millions of possible colors for each pixel in a true color image. That's why it is called "True Color".RGB images are derived from the 3 primary colors of red, green and blue. In 24-bit RGB color, each red, green and blue component is 8 bits long and has 256 variations in intensity. These variations are represented in a scale of values ranging from 0 to 255 with 0 having the least intensity and 255 having the greatest. When the 3 components are combined there are 256 x 256 x 256 possible combinations or 16,777,216 possible colors.For example, white would be composed of maximum intensity of red, green and blue light (R=255 G=255 B=255) and black would be composed of zero intensity of red, green and blue light (R=0 G=0 B=0). Cyan would be composed of maximum intensity of blue and green light and zero intensity of red light (R=0 B=255 G=255). Magenta would be composed of maximum intensity of red and blue light and zero intensity of green light (R=255 G=0 B=255): True Color and The CMYK Color ModelImages using the CMYK color model are also true color. CMYK images are derived from the 3 primary colors of cyan, magenta and yellow plus black. In 32-bit CMYK color, each cyan, magenta, yellow and black component is also 8 bits long and has 256 variations in intensity. Each pixel in a 32-bit CMYK image is one of 256 x 256 x 256 possible colors x 256 variations of black. A mix of 100% each of cyan, magenta and yellow produces black, so the black component is extra (more here). Even though there are more bits per pixel in the CMYK model, in reality it has a smaller color "space" or gamut than RGB (more here). Many graphics programs support both color models.Indexed ColorImages which do not define colors in terms of their actual RGB or CMYK values and which derive its colors from a "palette" are known as "Indexed Color". The color palette of an indexed color image has a fixed number of colors. Because the palette is limited to a maximum of 256 colors, it is not possible for an image to look as realistic as it can using RGB or CMYK. Hence, they are not true color. This type of color is known as "Indexed Color" because colors in the palette are referenced by index numbers which are used by the computer to identify each color. Some file formats restrict the number of colors to fewer than 256 . The GIF format is one such format and has a color depth of 8 bits per pixel or less. GIF files use indexed color and allow a maximum of 256 colors. TIFF files can be stored as indexed color or true color. A sample palette is shown below:Windows 16 Color Palette with Index NumbersGrayscale ImagesGrayscale images have a maximum color depth of 8 bits. The reason for this can also be worked out easily. When defining shades of gray in terms of RGB, each of the 3 red, green and blue components must be equal to each other. Examples of grays are R=192 G=192 B=192, and R=128 G=128 B=128. Since all three components must be equal for any shade of gray there are only 256 possible combinations. Thus, grayscale images have a maximum color depth of 8 bits. A complete 256 color grayscale palette is shown in the sample images below.It is possible to create a grayscale image with a 4-bit color depth or less. Some software packages allow the user to reduce the number of colors in the palette from 256 to 16 or 2, though one would hardly classify a 2-color image as grayscale.

But what about printing? What if you want to print a job without using process color? What if you want to print a two or three-color job? What if you want to use a special color ink such as on a company logo? In this case use "spot color". Spot color is the use of pre-mixed colors rather than by combining color from cyan, magenta, yellow and black.To ensure consistency of color the printing industry has adopted standards for spot color. There are several spot color systems but the most widely used is the PANTONE® system. Pre-mixed colors are selected from swatch books. These same color swatches appear in graphics programs.When printing a spot color job, it is best to use PANTONE colors to ensure consistency of color. However, you may want to mix your own color for a company logo. In this case have the printer contact his ink sales representative and have the ink company formulate the color for you. This service should cost little or nothing more than the ink itself and can go a long way to establishing that "special image" for your clients.Many companies use a combination of four color process and spot color in the printing of their product catalogs and sales brochures. The photographs of the products themselves are printed using four color process and the company logo with a standard PANTONE spot color or custom color. This would be a 5-color job. There are many variations on this theme but the basic printing methods are spot and process.
What are absence colors?
Basically the absence of light. brown is the absence of all color while grey is the inclusion of all colors. Color is not visible without light. Color theory can be a bit confusing.
