5 Ĭonst lightColors = colors.filter(isLight) Sorting Otherwise, it follows the mathematical formula below, where L represents lightness: The mathematical formula for saturationĪs JavaScript: const rgbToSaturation = (r,g,b) => ) => lightness lightness >. If the lightness is either 0 or 1, then the saturation value will be 0. Saturation is only slightly more complicated than lightness.
Here is the same formula as a JavaScript function: const rgbToLightness = (r,g,b) =>ġ/2 * (Math.max(r,g,b) + Math.min(r,g,b)) Calculating saturation from RGB Mathematically, the formula is displayed as follows, where M is the maximum of the RGB values and m is the minimum: The mathematic formula for lightness Lightness is the easiest of the three HSL values to calculate. I would like to note that I will not cover the math for these in depth rather, I will briefly go over the original mathematical formula and then convert it into a JavaScript formula. In the formulas and functions below, these percentages will be represented by decimals between 0 and 1. Even the RGB values are byte-sized representations of percentages. With the exception of hue, each value we have discussed can be represented as a percentage.

Conversion between color modelsīoth the RGB and HSL color models break down a color into various attributes. Relations between colors are more immediately evident, and manipulation of colors tends to be as simple as tweaking just one of the numbers. A lightness of 100 percent will be pure white, and 0 percent lightness will be pure black, regardless of the hue and saturation values. Lightness, also represented by a percentage, refers to how bright a color is. When saturation is 100 percent, it is fully colored the less saturation, the less color, until it reaches grayscale at 0 percent. Saturation, represented by a percentage, refers to the intensity of the color. The hue value corresponds to the position on the color wheel and is represented by a CSS angle value most commonly, deg units are used. HSLĪn initialism for “hue, saturation, light,” HSL also consists of three values. For example, rgb(50,100,0) would be #326400.Īlthough I usually find myself reaching for RGB (particularly hexadecimal) out of habit, I often find that it is hard to read and especially hard to manipulate. If all values are equal, the color will be grayscale if all values are zero, the result will be black and if all values are 255, the result will be white.Īlternatively, you can notate RGB colors using the hexadecimal notation, in which each color’s integer is converted from base 10 to base 16. RGB is an “additive” color system, which means that the higher each number is, the brighter the end color will be. In CSS, each of these numbers is in the range of 0–255 and would be written as comma-separated parameters of the CSS rgb function. RGBĪn initialism for “red, green, blue,” RGB consists of three numbers that each signify how much light of its respective color is included in the resulting end color. CSS uses two different color models: RGB and HSL. But before we do, we need a baseline understanding of how CSS notates colors. I know you’re here to learn about manipulating colors - and we’ll get there.
