Color depth is defined as what?

Color depth is defined as what?

• A. The number of different colours representable by a single pixel
• B. The brightness of a single pixel
• C. The total number of pixels on a screen
• D. The frame rate of display

Answer: (A)

Color depth is the number of different colors a single pixel can represent, determined by how many bits are used for that pixel. The more bits per pixel, the more colors can be displayed, which allows smoother color transitions and more realistic images. For example, 8 bits per pixel yields 256 possible colors, while 24 bits (8 bits per RGB channel) yields about 16.7 million colors. This concept is distinct from brightness (how light or dark a pixel appears), resolution (the total number of pixels on the screen), and frame rate (how many frames are shown per second). Therefore, color depth directly describes how many colors a single pixel can display.
