Provided Converters. Enter hue in degrees (°), saturation and value (0..100%) and press the Convert button: But we still have some! In short, color is the visual byproduct of the spectrum of light as it is either transmitted through a transparent medium, or as it is absorbed and reflected off a surface. ) n After such a transformation, hue is precisely the angle around the origin and chroma the distance from the origin: the angle and magnitude of the vector pointing to a color. If you think color is a mysterious woo-woo rainbow of ethereal magic, you’ll be disheartened to find out that every computer on the face of the planet represents every possible color it can output with just 3 numbers ( 0 ∈ − ∘ example in docs The HSB model is also known as HSV (Hue, Saturation, Value) model. Value must be in range [38] Furthermore, hue is defined piecewise, in 60° chunks, where the relationship of lightness, value, and chroma to R, G, and B depends on the hue chunk in question. with C = 0) are assigned a hue of 0° for convenience of representation. ) ) . , That is, for colors with R = G = B, any of the four formulations yields a lightness equal to the value of R, G, or B. min H Unfortunately, it's all too easy to use color ineffectively, especially if you are not trained in visual design. [ H In HSV, tinting alone reduces saturation. [ 6a. ≥ [F][G], More precisely, both hue and chroma in this model are defined with respect to the hexagonal shape of the projection. a Most of the computer graphics papers and books discussing HSL or HSV have a formula or algorithm describing them formally. ). ] Now that users can choose colors visually, or choose colors related to other media (such as PANTONE), or use perceptually-based systems like L*u*v* and L*a*b*, HSB and HLS should be abandoned.[40]. In above formulas the {\displaystyle H_{V}\in [0^{\circ },360^{\circ }]} For instance, a 1982 study by Berk, et al., found that users were better at describing colors in terms of HSL than RGB coordinates, after being taught both systems, but were much better still at describing them in terms of the natural-language CNS model (which uses names such as "very dark grayish yellow-green" or "medium strong bluish purple"). n Mixtures with white are called, Fig. In the same issue, Joblove and Greenberg[11] described the HSL model—whose dimensions they labeled hue, relative chroma, and intensity—and compared it to HSV (fig. − Therefore, any two colors (R, G, B) and (R − m, G − m, B − m) project on the same point, and have the same chroma. The R,G,B functions of Using the same name for these three different definitions of saturation leads to some confusion, as the three attributes describe substantially different color relationships; in HSV and HSI, the term roughly matches the psychometric definition, of a chroma of a color relative to its own lightness, but in HSL it does not come close. {\displaystyle k,n\in \mathbb {R} _{\geq 0}} n Compare to a L*C*h Color Wheel. ( is constructed as follows: This definition introduces discontinuities, corners which can plainly be seen in horizontal slices of HSL or HSV.[39]. In the lower part of the adjacent diagram, this is the ratio of lengths OP/OP′, or alternately the ratio of the radii of the two hexagons. Descriptions in terms of hue/lightness/chroma or hue/lightness/saturation are often more relevant. . Often, we must make use of an image editor to render something truly monochromatic. Let’s break those down first. 0% means totally dark or black; 100% means full brightness, with the color is fully determined by the hue and saturation. In the example below (fig. 0 is red, 120 is green, 240 is blue. Given a color with hue H ∈ [0°, 360°], saturation SL ∈ [0, 1], and lightness L ∈ [0, 1], we first find chroma: Then we can find a point (R1, G1, B1) along the bottom three faces of the RGB cube, with the same hue and chroma as our color (using the intermediate value X for the second largest component of this color): In the above equation, the notation 7). Location, location, location. Though none of the dimensions in these spaces match their perceptual analogs, the value of HSV and the saturation of HSL are particular offenders. Overlap (when {\displaystyle k,n\in \mathbb {R} _{\geq 0}} we change values bigger than 1 to exact 1. This 1916 color model by German chemist. Poor use of color results in designs that look unprofessional, dated, confusing, or just plain ugly. Saturation is also referred to as intensity and chroma. {\displaystyle H\in [0^{\circ },360^{\circ }]} To keep things simple, we’ll limit this guide to 3 types of palette selection: monochromatic, colour matching, and complementary.
