How to Adjust Hues in Adobe Photoshop ?



Open the file or image you want to edit through Photoshop. Do so by typing Ctrl+O (or Command+O for Mac users) on the keyboard.

Open the hue/saturation adjustment. This can be done in one of two ways. The first option is to go to image>adjustments>hue/saturation (type in the shortcut Ctrl+U or Command+U). Alternatively, you can just click on the "create adjustment layer" icon. For current purposes, the second option is ideal.

Click on the “create adjustment layer” icon.

Wait for the adjustment window and layer to appear. This may take a couple of seconds.

Drag the window towards your image. Drag the window by clicking and holding it as you move your mouse.

Move the hue slider left or right. The adjustment layer should be beside your image file. By moving the hue slider, you will be able to see the gradual change of colours on your image.

Experiment with the saturation slider. Drag the slider to the left for a lesser amount of colour on the picture or for a duller grey image.

Drag the slider to the right for more vibrant colours on the image.

Experiment with the lightness slider. Drag the slider to the left for a darker image; lightness adjusts the amount of black/white (in this case more black) on the image.

Drag the lightness slider to the right for a lighter image.

Click “Colorize” on the Hue/Saturation adjustments window. Then play with the hue slider to look for the colour you want to apply on your image.

Using the brush tool, paint over your image to reveal some of the original colours of the image. Paint over your image by unlinking and selecting the layer mask on your adjustment layer. Make sure also that the colour you're using is black as you paint over the image and on the layer mask.

You have learned the basics of how to adjust hues on an image using Photoshop.
