Built-in Mathematica Symbol

Blend

Blend[{col₁, col₂}, x]
gives a color obtained by blending a fraction

of color col₁ and x of color col₂.

Blend[{col₁, col₂, col₃, ...}, x]
linearly interpolates between colors col_i as x varies from 0 to 1.

Blend[{{x₁, col₁}, {x₂, col₂}, ...}, x]
interpolates to give col_i when x=x_i.

Blend[{col₁, col₂, ...}, {u₁, u₂, ...}]
blends all the col_i, using fraction u_i of color col_i.

Blend[{col₁, col₂, ...}]
blends equal fractions of all the col_i.

MORE INFORMATION

In Blend[{col₁, ..., col_n}, {u₁, ..., u_n}] the u_i are normalized to have total 1. »

Blend implements additive color mixing, as appropriate for color light sources or light-generating displays.

Scope (5)

Linear interpolation between two colors:

Linear interpolation between two colors and two opacities:

Linear interpolation between multiple colors uniformly:

Linear interpolation between colors at specific values:

Blending colors with equal weights:

Blending colors with specified weights:

Generalizations & Extensions (1)

Different colors can be given at the single position to generate discontinuity:

Applications (1)

Use Blend to construct a ColorFunction from base colors:

Properties & Relations (7)

The weights are always normalized, so that the sum becomes 1:

The position values are always sorted:

When colors are specified using the same color space, that space is used for interpolation:

When colors are specified using different color spaces, interpolation happens in the RGB space:

Lighter is a special case of Blend:

Darker is a special case of Blend:

ColorData contains a large number of predefined Blend colors called "Gradients":

Gradients can be called by their names only:

Polygon supports equal weight blending of VertexColors:

Possible Issues (1)

Values outside of the 0, 1 range will be clipped:

In plot functions, use ColorFunctionScaling to control global scaling of variables:

Neat Examples (2)

Use Blend with plots to generate synthesized textures:
