What does this sentence mean?Thanks

we have a color depth of 24 (8 * 3) bits and we can also infer that we could use 2 to the power of 24 different colors.
Can you give me an example?

Hi @1-riverfish,

Assuming we have 3 rgb channels: R, G and B. Each channel requires a byte (8bits). If one needs to define a single color he/she will use 24bits (or the three channels).

Let's define some color out of my mind:

black: 0 (R), 0 (G), 0 (B)
black1: 1 (R), 0 (G), 0 (B)
...

Thus we can infer that we can have 2^24 color option, is it more clear for you?

Thank you, I understand now. I find some pictures to explain the 4:4:4,4:2:2 ,4:1:1,4:2:0 Maybe it is useful.Thank you again. Sent from YoMail
