Apply LUTs in Pixelmator Pro

LUT (or the "lookup table") offers a means of changing, managing, and matching colors, and is commonly used in cinema and photography. LUTs are similar to the color adjustment presets in Pixelmator Pro. Both are sets of color, shadow, and contrast adjustments that combined give an image a particular look and feel. In fact, LUTs themselves can be used together with Pixelmator Pro-native color adjustments.

What's different about LUTs, is that unlike the color adjustments presets which are Pixelmator Pro-exclusive (i.e. can be created and used within the Pixelmator ecosystem only), LUTs are universal. This means that the same LUT can be used across different editing programs and different mediums. With that, all sorts of handy workflows become possible. For instance, you can use LUTs to apply a look of any image you've edited in Pixelmator Pro to a video you're working on in Final Cut Pro. See Using Pixelmator Pro to color grade video in Final Cut Pro to learn more about this workflow.

Pixelmator Pro supports LUTs in the .cube file format. If read as plain text, the .cube file will often feature a list or table of colors expressed by values ranging from 0.0 to 1.0. Pixelmator Pro can then use these lists or tables to look up exactly to which new color values the already existing values should be changed. Once that's done, the pixels featuring those colors (or their closest shades) will change in the image as well.

Apply a custom LUT to an image

In Pixelmator Pro, you can choose from 5 different collections of pre-made LUTs that come with Pixelmator Pro or apply the custom LUTs you've installed yourself. Since LUTs work like any other color adjustment, they can be non-destructively applied to individual layers or layer groups and combined with other adjustments.

  1. Do one of the following:
    • Choose Format > Color Adjustments > Custom LUT (from the Format menu at the top of your screen) and choose a LUT from the list.
    • In the Tools sidebar, click and turn on Custom LUT or add it from the Customize menu at the bottom of the Color Adjustments pane. In the Custom LUT pop-up menu, choose from the available LUTs.
  2. (Optional) Drag the Intensity slider to control the strength of the LUT or how it blends with the other color adjustments.

Tip: You can see how LUTs will look like before applying them by hovering the pointer over the name of the LUT.

Show Original: Click the Show Original button or press Control ⌃ + M on your keyboard to see what the image looks like without any color adjustments.

To reset all Color Adjustments, click Reset at the bottom of the Color Adjustments pane.

Apply a custom LUT as a color adjustments layer
  1. To create a color adjustments layer, do any of the following:
