IHlsColor Interface

Provides access to members that control the HLS color model.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

IHlsColor maintains information about a Color by using the HLS (Hue, Saturation, Lightness) color model. This color model is similar to the HSV color model, however, HLS colors use Lightness instead of Value. The Hue property may be set to a number between 0 and 360, indicating in degrees where the hue lies on the color wheel. The Saturation property is a number between 0 and 100 indicating the saturation, or purity, of the color, and the Lightness property is a number between 0 and 100 indicating the lightness, or paleness, of a color. Regardless of other properties, a lightness of 0 is always black, and a lightness of 100 is always white. All of the properties have a default of 0; therefore, the default HLSColor is black.
