Colour Depth

Colour depth refers to the number of bits per pixels a computer monitor can display to represent a specific colour. The more bits per pixel, the more colours can be displayed by the monitor, thus meaning that the higher the bit per pixel the better quality the monitor has.

The first graphic cards only supported 1-bit colour which means that the colour was monochrome. But now a days due to our technological advancements computers can store at least 32-bits of colour which displays about 16 million colours



Down below I am going to show the difference between;  24 bpp, 16 bpp, 12 bpp, 10bpp, and 8 bpp.
(bpp- Bits per pixel)

24 Bits Per Pixel - it is the most clear out of all



16 Bits per Pixel - as one can see there is a  minimal change from the 24 Bpp

12 Bits per Pixel - the change is now more visible from the 16bpp


10 Bits Per Pixel - The change is now becoming more visible, the lower the bits per pixel is.


8 Bits Per Pixel - now the change is clearly evident from the other BPP's as there are now less colours which are being used when 8 bpp are being used.
