8.55. Colorize

The Colorize filter renders the active layer or selection into a grayscale image as seen through colored glass. You can use it to apply a “Sepia” effect to your image, for example.

	Namig
	This filter uses the HSL color model. Previous versions of GIMP included a similar filter, “Colorify”, which used the HSV model instead. That effect can still be reproduced using specific parameters (such as Saturation=1.0 and Lightness=-0.5), or by specifying Saturation=0.0 and applying the color tint as a separate step.

Obarvanost

Which tint to apply to the image. Note that while Hue is normally shown in degrees (from 0 to 360), here it is shown from 0.0 to 1.0. A Hue of 36° would be input as 0.1, for example.

Nasičenost

The intensity of the color tint, if any. This is also expressed in a range of 0.0 to 1.0, with 0.0 yielding a grayscale conversion only, and 1.0 applying a pure RGB color tint (of the selected Hue).

Lightness

The brightness of the result. This is expressed in HSL terms, along a range of -1.0 (black) to 0.0 (normal) to +1.0 (white).

Color

Using the color button (or the color picker) you can quickly select the color used to colorize your image: selecting a color here will adjust the sliders above to match.
