You can change the color of regions to identify sections of your arrangement, distinguish between track types, or for other uses. Newly recorded or added regions use the color of the track channel strip.
In Logic Pro, select the region or regions you want to change.
Note: If you select all regions on a particular track, and no regions on other tracks are selected, coloring them alters the hue of all selected regions. This also changes the color of the selected track’s channel strip.
Choose Logic Pro > Settings > View, then click the Tracks button. In the Display Track settings pane, make sure that the Region Color pop-up menu is set to Individual.
Note: If the Region Color pop-up menu is set to As Track Color, you cannot color regions individually.
Control-click one of the selected regions, then choose Name and Color > Show/Hide Colors from the shortcut menu (or press Option-C).
Click a color.
In Logic Pro, select the regions you want to change.
If all regions are on a single track, click the track’s header to select all regions (when the "Select regions on track selection" checkbox in the General Editing settings is selected).
Choose Functions > Color Regions/Cells by Track Color from the Tracks area menu bar.
The colors of all selected regions are replaced with the colors of the corresponding tracks.
Tip: This feature is handy after copying or moving regions between tracks, when you may find that the Tracks area resembles a patchwork quilt.
