Step 1: Open your illustration
Start by opening your illustration in Adobe Photoshop. To do this, press File > Open from the menu and browse to the location of your image file.
Step 2: Select the Magic Wand Tool
Find the Magic Wand Tool in the toolbar. If you don’t see it immediately, it might be nested with the Quick Selection Tool. Click and hold the Quick Selection Tool to reveal it.
Step 3: Select the area to recolor
Click on the area of your illustration that you want to recolor. If the selection isn’t perfect on the first try, hold the Shift key (or the ⇧ symbol on Mac) and click additional areas to add them to your selection.
Step 4: Click on “Create new adjustment layer”
You can find it by a half-full circle symbol:
Or find it in Layer > New Adjustment Layer > Hue/Saturation
It will make a new layer for you to recolor the selected area.
Step 5: Recolor the selection
With the new layer selected, go to Adjustments > Hue/Saturation. Alternatively, Photoshop can show it to you automatically on the right side. Here, you can slide the controls for Hue, Saturation, and Lightness to change the color of the selected area. Slide the Hue bar until you achieve the desired color.
If you want to recolor more objects, deselect your area and select others. You can select several different areas by holding shift (or the ⇧ symbol on Mac).
Step 6: Save your work
Once you are satisfied with the recoloring, save your file by pressing File> Export as and selecting the desired format and location to save your artwork.
