# photobot.Layer.color()

## Syntax

    canvas.layers[i].color()

## Description

Sets the blend mode of layer i to color. Replaces the hue and saturation of the bottom layer with the hue and saturation of the hued layer, while retaining the bottom layer's brightness.

Colorizing works significantly slower than other blend modes, because it is a blend mode native to PhotoBot and not of the underlying Python Imaging Library.

## Example

    photobot = ximport("photobot")
    canvas = photobot.canvas(100,100)
    canvas.layer("robot.jpg")
    i = canvas.fill((185,255,0))
    canvas.layers[i].color()
