On Photoshop, there are different shades to use for rosy cheeks. Down below are a few directions you can use:
1. Create one layer
2. Select the “Color Picker” (Foreground Color) on the bottom left hand corner
3. After you select a radiant shade, use the brush tool to color your cheeks
4. Once you have filled in your rosy cheeks, scroll your mouse to the right hand side, click on “Normal” and click on “Multiply.”
