When you need to change the color of something in a photo, look no further than Hue/Saturation Adjustment Layers! Learn how to use Hue/Saturation to target specific colors in an image, and then make adjustments to the hue, lightness, and saturation to change those colors to whatever you want.
This is Day 7 of our 30 Days of Photoshop series. Follow along with all 30 episodes as we explore the the magic of Photoshop together!
One of the most commonly used Adjustment Layers in Photoshop, Hue/Saturation has a wide variety of applications. Want to change the color of a background to match a subject’s wardrobe? Need to provide a client with product photos in a variety of different color options? Have a subject with some skin redness that you want to clear up? Hue/Saturation Adjustment Layers can handle each of these situations (and more!) with ease.
Hue, Lightness & Saturation
So what is the difference between hue, lightness, and saturation and why do we need a slider for each?
Hue is just another word for color. This slider will determine whether something will appear green, purple, or orange–any color along the spectrum.
Saturation is the intensity of the chosen color. As you push this slider to the right, the color will appear more bright, pure, and vivid. Push it to the left, and the color will begin to appear more gray and dull, eventually shifting to a purely gray value.
Lightness describes the amount of black or white that is mixed with thee hue. Add more black and the color will appear darker. More white and it will appear brighter.
Not only will a Hue/Saturation Adjustment Layer allow you to dial in each of these attributes, it also allows you to select a specific color range from a photo that you want to change. Let’s say that you wanted to change a red wall to yellow to match a subject’s shirt. You can use the eyedropper tool and sliders near the bottom of the dialog to select only the reds in the wall, and then use the top three sliders to shift the color to yellow.
