Using the CSS3 HSL declaration is also used to set the color. What's next? HSLA? Yes, this is the same as the Rgba effect.The HSL declaration uses Hue Hue (H), saturation saturation (s), and Luma lightness (L) to set the color.Hue is derived from the color dial: 0 and 360 are red, close to 120 is green, 240 is blue.Saturation value is a percentage: 0% is grayscale, 100% saturation is highestThe lightness va

Introduction to HSL FunctionsWhat are the specific functions of the HSL color function, and what is the function of it: HSL ($hue, $saturation, $lightness): Creates a color from the values of Hue (hue), saturation (saturation), and brightness (lightness); Hsla ($hue, $saturation, $lightness, $alpha): Creates a color from the values of Hue (hue), saturation

Transferred from: http://blog.csdn.net/aniven/article/details/2205851RGB and HSL (also called HSB/HSV) are two color spaces, namely: red, green, Blue (red,green,blue) and hue, saturation, brightness (Hue,saturation,lightness or brightness or value), the former is suitable for machine sampling, the current display color is composed of these three colors, and the latter more in line with human visual sense, such as people generally express a color will

Article Description: Color-born mind: humanized HSL model. For visual designers, RGB, CMYK or whatever is as familiar as the right-hand person. But if only in the way of mental arithmetic, do not use the Photoshop color Picker or any similar tool, you can quickly say "Begonia red" corresponding to the RGB color value? If you add a little orange to go in, increase the brightness a little, the color value is how much?It's hard to answer

HSL is a very intuitive way to choose colors. If you need to "darken a little more" or "lighten up a little bit", using the hexadecimal combination can be quite troublesome. Fortunately, through HSL, it's just a simple number change. HSL color model is a color standard of industry, by changing the hue (H), saturation (S), Brightness (L) of three color channels a

In the computer, RGB (red, green, blue), red, green, blue, and HSL (hue, saturation, lightness) colors, saturation, and brightness are our two most commonly used color formats, in some cases, we need to convert them accordingly. The principle of conversion between them is as follows: (more color format conversion can be viewed: http://www.easyrgb.com/index.php? X = math) RGB ------ HSL code Code h

Using the CSS3 HSL declaration is also used to set the color. What's next? HSLA? Yes, this is the same as the Rgba effect. The HSL declaration uses tonal hue (H), saturation saturation (s), and brightness lightness (L) to set the color. Hue derived from the color plate: 0 and 360 are red, nearly 120 are green, and 240 is blue. Saturation value is a percentage: 0% is grayscale, 100% saturation is the high
