The Color Link effect colorizes one layer with the average pixel values of another layer. This effect is useful for quickly finding a color that matches the color of a background layer.

This effect works with 8-bpc color.

Source Layer

The layer from which to sample colors. If you choose None, the layer to which the effect is applied is used as the source layer, taking into account any masks and other effects applied to the layer. If you choose the layer’s name from the menu, the source layer without masks and effects is used.

Sample

Specifies what values are sampled and what operation is performed on them.

Clip

The percentage of pixels to ignore at the extreme channel values. This clipping is useful for reducing the influence of noise or other nonrepresentative pixels.

Stencil Original Alpha

The effect places a stencil of the layer’s original alpha channel over the new value.

Opacity

The effect’s opacity. The result of the effect is blended with the original image, with the effect result composited on top. The lower you set this value, the less the effect affects the layer. For example, if you set this value to 0%, the effect has no visible result on the layer; if you set this value to 100%, the original image doesn’t show through.

Blending Mode

The blending mode to use to combine the effect result with the original layer. These blending modes aren’t available when averaging alpha channel values in the layer.
