§ 25.7 - Power Colorizing Tutorial

How to produce Duotones, Quadtones... Anytones!

One of the most overlooked operations in F/x is Standard / Remap. This short note should serve to help get you thinking.

Remap works with two palettes. It takes colors in the image and compares them to colors in the first, or "from", Palette. When a color is close to one in this "from" Palette, it changes the color to the corresponding color in the second, or "to", Palette. That can be quite interesting, and complex to handle, with a color image.

However, if you first change the image to monochrome using Photo / Monochrome, then set the "from" Palette to 256 grey levels, the operation will map the Remap palette directly onto the image's luma, which is the perfect thing for creating duo- tri- or even higher "tones."

The best way to go about this is to open the "from" Palette, set it to 256 colors, then set it to black through white. That sets up your source of 256 grey levels.

Then open the "to" Palette, set it to black at the upper left and white at the lower right. Then change color #128 to a fully saturated color (it doesn't matter what color). Then make two Luma Spread ranges from each end of the Palette to this fully saturated color.

The Palette now contains a ramp of saturation from none at the upper left to maximum in the middle, and a ramp of saturation from maximum to none at the end.

Now change some of the colors in the palette using the color wheel only, which ensures you aren't changing the color saturation.

Once you have these key colors, just make more luma spread ranges between them. Now you have a multi-tone palette which follows a single saturation ramp.

You can also experiment with altering the mid-Palette color saturation levels prior to making your various Luma Spread ranges.

Here are some examples:

yellow, green


green, yellow, red, purple, blue, aqua, pink

This is the remap palette for the sep-tone
