Knowra HWB color model HWB color model The HWB color model represents a color by its hue, whiteness, and blackness. It is designed to make intuitive color selection easier than specifying red, green, and blue intensities.
Hue : Hue is the dimension of color associated with distinctions such as red, green, and blue. HWB uses hue to choose a point around its color wheel.
Color wheel : A circular arrangement of hues that places related colors next to one another. HWB's hue coordinate follows a rotation around a color wheel.
CSS Color Module Level 4 : A W3C specification defining modern color notation and color-related features for CSS. It standardizes HWB syntax for use in web stylesheets.
HSL color model : The HSL color model represents colors through hue, saturation, and lightness. HSL varies saturation and lightness instead of specifying white and black amounts.
Whiteness : Whiteness is the proportion of white mixed into a color in the HWB model. Increasing whiteness moves an HWB color toward white.
Color space : A color space is a mathematical system for representing colors as coordinates. HWB is one coordinate system within the broader family of color spaces.
CSS hwb() function : The CSS hwb() function specifies a color using hue, whiteness, and blackness values. It is the direct CSS expression of the HWB model.
HSV color model : The HSV color model represents colors through hue, saturation, and value. HSV's value-and-saturation coordinates produce a different intuitive adjustment scheme.
Blackness : Blackness is the proportion of black mixed into a color in the HWB model. Increasing blackness moves an HWB color toward black.
Additive color : Additive color describes colors formed by combining emitted light, typically red, green, and blue. HWB ultimately specifies colors intended for screen-based light emission.
