How to Change Someone's Skin Color to Green in Photoshop
Whether you're a fan of the Invisible Hulk, the Wicked Witch of the West and Shrek or just feel like going green, getting your skin colored green may leave unwanted lasting results. Instead of the real thing, use Adobe Photoshop to turn skin color green in just minutes.
Open "Photoshop." Click the "File" menu. Click "Open." Locate the photo of the person with the skin to turn green, and double-click the file name. When the photo opens, press the "Ctrl" and "+" keys on the keyboard to zoom in on one portion of the skin, which you'll be doing part by part.
Click the "Lasso" tool. Draw an outline around that part of the skin, such as an arm. Try to avoid capturing any clothes or background in the outline. Blinking lines appear.
Click the "Image" menu, select "Adjustments" and click "Hue/Saturation." Drag the window to the side so you can view both the skin and the window.
Slide the "Hue" bar to the left or right until the skin is the ideal color green. Direction will vary on the person's existing skin color and picture lighting. Note the number that appears in the "Hue" box, and click the "OK" button.
Repeat the "Lasso" process on the next part of skin. Repeat the "Image," "Adjustments" and "Hue/Saturation" process, but instead of sliding the bar, type in the number. This gets the skin all the same color green. Continue until all showing parts of the skin are colored green.
