The color encoding we’re using is RGB. What does this mean, in terms of the amount of memory required to represent color? Is there a limit to the number of colors that we can represent? Are there enough colors representable in RGB?

What will be an ideal response?

RGB means that every color is made up of a combination of three different primary colors, each represented by eight bits each. This gives us a total of twenty-four bits of color possibilities, for a total of 16,777,216 colors. Humans can see more than sixteen million colors, but since no device exists that can express all the color variations we can see, the RBG model is enough.
