Photoshop’s Replace Colour adjustment is a quick and efficient way to swap one colour for another.
Start by going to the top menu and select: Image > Adjustments > Replace Color. Tap the eyedropper tool in the image to select the colour to replace– .
The next step is to decide on the colour you want to change it to (Result). You can either slide the "Hue" slider or click on the colour box to select your chosen colour. You can also alter the "Saturation" and "Lightness".
You will probably find that only part of the colour has been changed so the final step is to use the eye dropper tool with the "+" sign to increase your selection.
