How many colors can be displayed in 24-bit color?
16.7 million
Background
24-bit color displays 16.7 million different shades. Each of the three base colors red, green, and blue uses 8 bits with 256 values each. The human eye can only tell about 10 million colors apart. That is why 24-bit is enough for photos and websites. Pro monitors now use 30-bit for even smoother color gradients.
