How to Use Brush Blending Modes in Adobe Photoshop
Blending modes look at the tonal quality of the pixels you are painting on and the color you are painting with to affect the result in various ways. In this example, we will colorize a grayscale image using a blending mode, so as not to destroy the shaping of the image created by the gray.
This feature works the same in all recent versions of Adobe Photoshop: CS5, CS6, and Creative Cloud (CC).
- Open any true grayscale image. For this example, we will use a grayscale image of a baby.
- In order to colorize an image, you will first need to convert it to RGB. Go to Edit > Convert to Profile. In the dialog box, select Working RGB from the Destination Space Profile drop-down menu and click OK.
- Click the Foreground Color at the bottom of the Toolbar to open the Color Picker, set the color values, and click OK.
- Select the Brush Tool and then go to the Options Bar, click the Mode drop-down menu, and select Color.
- To prepare to colorize an element, go to the image and right-click (PC)/Control-click (Mac) anywhere to open the Brush Preset Picker. Select a brush (we have selected the Soft Round brush) and set the size and the Hardness. Press Enter (PC)/Return (Mac) to close the picker.
- Go to the image and start painting the element you wish to colorize. In this example, we colorized the flower behind the baby's ear. Vary your brush size as needed using the bracket keys. (You can zoom in for a better view.)
