Editor to share with you what hsl color blending refers to, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Hsl color blending is a representation of the points in the RGB color model in the cylindrical coordinate system, HSL is hue [Hue], saturation [Saturation], luminance [Lightness].

HSL is a representation of points in a RGB color model in a cylindrical coordinate system. HSL is hue (Hue), saturation (Saturation), luminance (Lightness).

The hue (H) of HSL is the basic attribute of color, that is, the color name, such as red, yellow and so on. Hue is made up of primary color, intermediate color and complex color. Hue is the primary feature of color and the most accurate standard to distinguish different colors.

The saturation (S) of HSL is the freshness of the color, also known as the purity of the color. The saturation depends on the proportion of the color component and the achromatic component (gray) in the color. The larger the color component is, the greater the saturation is, and the larger the achromatic component is, the smaller the saturation is. Take a value of 0-100%.

The brightness (L) of HSL is the degree of light and shade of a color, which is mainly a visual experience determined by the intensity of light. Colors with the same hue may differ in light and shade. Generally speaking, the stronger the light, the brighter it looks; the weaker the light, the darker it looks.

The purpose of HSL

It is usually used in computer graphics applications. The HSV color wheel is often used in a variety of application environments where the user must select a color to apply to a particular graphic element. In which the hue is represented as a ring; a separate triangle can be used to represent saturation and lightness. Typically, the vertical axis of the triangle indicates saturation, while the horizontal axis indicates lightness.

It can also be expressed as a cylinder similar to a cone, the hue varies along the outer circumference of the cylinder, the saturation varies along the distance from the center of the cross section, and the lightness varies along the distance from the cross section to the bottom and top. This representation may be considered a more accurate mathematical model of HSV color space; but in practice the number of levels of saturation and hue that can be distinguished decreases as the brightness approaches black.

The above is all the contents of this article "what does hsl color blending mean?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
