Review question for upcoming exam:

What does it mean that a color has a higher value in HSV?

Answer 1

HSV (Hue, Saturation and Value) – defines a type of color space. It is similar to the modern RGB (Red Green Blue) and CMYK(Cyan, Magenta, Yellow and Key) models. The HSV color space has three components: hue, saturation and value. ‘Value’ is sometimes substituted with ‘brightness’ and then it is known as HSB. This color space describes colors (hue or tint) in terms of their shade (saturation or amount of gray) and their brightness value. The HSV model was created by Alvy Ray Smith in 1978. HSV is also known as the hex-cone color model.

Hue
In HSV, hue represents color. In this model, hue is an angle from 0 degrees to 360 degrees.

Angle   Color
0-60       Red
60-120 Yellow
120-180 Green
180-240 Cyan
240-300 Blue
300-360 Magenta

Saturation
Saturation indicates the range of grey in the color space. It ranges from 0 to 100%. Sometimes the value is calculated from 0 to 1. When the value is ‘0,’ the color is grey and when the value is ‘1,’ the color is a primary color. A faded color is due to a lower saturation level, which means the color contains more grey.

Value
Value is the brightness of the color and varies with color saturation. It ranges from 0 to 100%. When the value is ‘0’ the color space will be totally black. With the increase in the value, the color space brightness up and shows various colors.

Advantages of HSV
The HSV color space is quite similar to the way in which humans perceive color. The other models, except for HSL, define color in relation to the primary colors. The colors used in HSV can be clearly defined by human perception, which is not always the case with RGB or CMYK.

conclusion - the higher the HSV value of colur, the higher will be its clarity for human eye.
