Colorize grayscale or 1-bit images
Select the bitmap object.
Make sure the Fill button in the Tools panel or Color panel is selected.
Use the Color panel to color the image with black, white, a process color, or a spot color.
Note:
If a grayscale image contains an alpha channel, you cannot colorize the image with a process color. Select a spot color instead.
