How many hues are there

Note that they are not spaced evenly. If 8 bits per channel are used in the HSV model, then there are less colors than in the RGB model with 8 bits per channel simply because some HSV triples map to the same color while every RGB triple defines a different color.

Yes, perhaps there is a formula to calculate this? I'd appreciate every answer with more insight into the subject: overlapping colors, bit-efficiency etc.

Yes, those are the colors that make up the rainbow as we know it. However, there is a hidden world of color that the human brain can barely comprehend coming at us from all directions.

All of the other colors in the world are technically just combinations of these core colors. Researchers who study color are pretty confident that there is a cap on the total possible number of perceivable colors in the world.

The way to figure out how many colors exist in the world is to start with how many shades of light the human eye can actually see. According to researchers , the answer is 1, shades of light. Within those shades, we can detect different levels of red-green shades. We can also see levels of yellow-blue shades.

It works out to about 10 million colors in the world that the human eye can see. Thus, the color red come as a light or a deep red, as a bright or dark red, or as strong or weak red. The richness or fullness of expression associated with a color is determined by the way in which we express its tone. As shown in Figure.

With this conceptual background, we are equipped to take a closer look at the world of color expression. Hues denote qualities that can be differentiated by color words such as red, yellow, green, blue or purple. These properties we describe as hues are not independent entities in themselves but form part of a color continuum which, like a ring, has no beginning and no end but forms a seamless continuum.

Between red and yellow there is an infinite number of colors possessing the elements of both these colors. We refer to these intermediate colors as yellowish-red, reddish-orange, orange, yellowish-orange, reddish-yellow and so on. As hues change, so do their emotional expressions, shifting from warm to cool. This dimension concerns the "warmth" of colors.
