How do you find the colour depth?
The colour depth of an image is measured in bits . The number of bits indicates how many colours are available for each pixel. In the black and white image, only two colours are needed. This means it has a colour depth of 1 bit….Colour depth.
| Colour depth | Available colours |
|---|---|
| 2-bit | 2 2 = 4 |
| 3-bit | 2 3 = 8 |
| 4-bit | 2 4 = 16 |
| 5-bit | 2 5 = 32 |

What is 48 bit color?
