How to change colors in Adobe Photoshop.

Apply an adjustment layer to your entire image, which will replace every instance of a certain hue. Or apply it to just one selection using a mask. To choose an object, use the Quick Selection tool.

In the Adjustments panel, select Hue/Saturation. This will create a new layer for you to work with. If you had previously selected an object using Quick Selection, your new layer will include a mask that prevents the rest of your image from being affected by the adjustment.

Select the color you’d like to replace by selecting it from the drop-down menu that says Master. Or use the Eyedropper tool to select the color right from your image.

In the Properties panel, use the Hue, Lightness, and Saturation sliders to change your selected color. The most dramatic changes, such as turning a blue sky orange, will happen with the Hue slider.

There are a few ways to tweak your adjustment to get it just right. Edit your layer mask to add or remove areas from the selection. Check the box next to Colorize to remove any tints from the previous color (note that this may remove texture). Use the plus and minus Eyedropper tools to add or subtract hues from your adjustment. Or manually move the markers on the adjustment color scale to affect a wider range of hues.

To remove or edit your color adjustment from the Layers panel, right-click (or Control-click) on your adjustment layer and select Delete Layer or Edit Adjustment. To change additional colors, add a new adjustment layer.
