color-interpolation

The color-interpolation CSS property is used in SVG to specify which color space to use for <linearGradient> and <radialGradient> SVG elements.

Syntax

css
/* Keyword values */
color-interpolation: auto;
color-interpolation: sRGB;
color-interpolation: linearRGB;

Values

auto

Indicates that the user agent can choose either the sRGB or linearRGB spaces for color interpolation. This option indicates that the author doesn't require that color interpolation occur in a particular color space.

sRGB

Indicates that color interpolation should occur in the sRGB color space. Defaults to this initial value if no color-interpolation property is set.

linearRGB

Indicates that color interpolation should occur in the linearized RGB color space as described in the sRGB specification.

Formal definition

Value auto | sRGB | linearRGB
Applies to <linearGradient> and <radialGradient>
Default value auto
Animatable discrete

Formal syntax

color-interpolation = 
  auto       |
  sRGB       |
  linearRGB

Example

In the first SVG, the color-interpolation property is not included on the <linearGradient> element and color interpolation defaults to sRGB. The second example shows color interpolation using the linearRGB value.
