In the context of colour depth, which description applies to 24-bit colour?

The description that 24-bit colour can display approximately 16 million colours is accurate because 24-bit colour uses three channels (red, green, and blue), with each channel having 8 bits. This means each channel can represent 256 different intensity levels (from 0 to 255). To find the total number of possible colours, you calculate ( 256 \times 256 \times 256 = 16,777,216 ) colours, which is often rounded to approximately 16 million for simplicity.

The other descriptions do not accurately represent 24-bit colour. The option that mentions only displaying black and white is incorrect as that refers to binary colour systems, not the rich colour capacity of 24-bit. Similarly, stating that it has the lowest colour representation contradicts the fact that 24-bit colour offers a high level of detail and colour diversity. Finally, suggesting that it is only suitable for text images is misleading; 24-bit colour is typically used for images requiring a broad range of colours and is widely utilized in photographs and complex graphics, rather than being limited to text.
