Duotone

Apply a duotone^* effect to the image.

The parameters are:

• h, the highlight color
• s, the shadow color
• o, the opacity (optional)

Colors can be expressed in any accepted format.
If an opacity is given, a semi-transparent version of the duotone image will be composited with the original image. This way the original colors will be visible under the choosen tones.
