In Photoshop, here’s a quick way to colorize a grayscale image to match a specific color in a layout:
First change its color mode to RGB (Image> Mode> RGB). Then choose your desired color as your Foreground color. (Here’s a super Photoshop tip that many people don’t know: to select a color from anywhere on your display — including documents in other applications such as QuarkXPress — just click and drag the Color Picker across your image and let go on any pixel on your display.)
Then add a Hue/Saturation Adjustment Layer by clicking the Create New Adjustment Layer icon at the bottom of the Layers palette.
In the Adjustments panel (or dialog box in earlier versions of Photoshop), click the Colorize checkbox, which will move the Hue slider to your Foreground color.
Now simply adjust the Lightness and Saturation sliders to your liking and you’re done!
