How many hex colors exists?

16,777,216 hex colors

In the hexadecimal color system, each color channel (red, green, and blue) is represented by a pair of hexadecimal digits. Since each hexadecimal digit can have 16 possible values (0 to 15), a pair of digits can represent 16 * 16 = 256 possible values.

Therefore, for each color channel, there are 256 possible shades. When you consider all possible combinations of shades for the three color channels, you get a total of 256 * 256 * 256 = 16,777,216 unique hex colors.

So, there are 16,777,216 possible hex colors in total. Each of these colors is a unique combination of red, green, and blue intensities, ranging from #000000 (black) to #FFFFFF (white) and all the colors in between.
