Colour Swapping in Photoshop

Replacing one colour for another is a useful trick that can completely transform an image; here's how it's done...

Capturing an aesthetically pleasing range of colours and hues is an essential part of colour photography, and Adobe Photoshop and Elements presents you with an array of tools to adjust, correct and replace colours to suit your needs. There are several scenarios whereby you may want to replace the colour of one element of an image with an alternative hue; there might be a distracting item in the background of your image that you want to tone down, or you may want to change an item of clothing or object to a more pleasing colour. You can even use it to give a vehicle a new paint job without the hassle of actually having it resprayed. Yellow London buses, green skies, pink elephants or purple grass; only your imagination is the limit.

One of the easiest methods is using the Replace Color Tool. This allows you to specify the colour that you wish to replace using the Eyedropper Tool, 
adjust the tolerance of this selection to encompass the full range of hues and shades, and choose the colour you want to replace it with all within a single dialog box before committing to the changes. It's worth noting that the tool isn't foolproof; the colour you replace needs to be of a similar lightness and saturation to the colour you introduce. For example, if you are trying to swap a bright yellow for a dark red, you may notice that the end result isn't as realistic as you might have hoped. The good thing is that the changes aren't applied until you click OK, so you can tweak the various parameters until you are happy with the final result. 


1. Prepare your image Before beginning, it's good practice to create a duplicate layer so any work you do is non-destructive. Doing this will also help when tidying the image in the later stages of the process. Go to Layer>Duplicate Layer and make sure that this new layer is selected in the Layers palette.

2. Pick your colour Go to lmage> Adjustments>Replace Color to bring up the Replace Color dialog box. Check the Localized Color Clusters box. The Eyedropper Tool will be selected, so simply click on the colour in your image that you wish to replace; this will highlight the area in white in the thumbnail preview.

3. Adjust the range Hold down the Shift key and click on the image to add further shades of the colour to the selection. If you select an area by mistake, holding down the aft key and clicking will remove that area from the selection. Use the Fuzziness slider to adjust the edges of the selection.

4.Swap the colour Use the Replacement Hue slider to introduce your new colour. You can then use the Saturation and Lightness sliders to tweak the colour's intensity and shade. You may need to readjust the Fuzziness slider to adjust the effect. Click OK once happy with the replacement colour.

5.Tweak the results Depending on your image, you may find that some other elements in your shot have changed colour without you wanting them to. Select the Eraser Tool, adjust your brush Size and Hardness in the top menu and brush over these areas to return them to their original colour. 

Final image Changing the colour of just one element in your photographs can completely alter the feel of the image. Experiment and see what you come up with. 

Alternative tools
As an alternative to the Replace Color menu, you can use the Color Replacement Tool. Click and hold on the Brush Tool to reveal the Color Replacement Tool. Set your Foreground Color to the colour you want to introduce and brush over the area of colour you wish to replace. The small crosshair in the centre of your brush is the area the tool will sample from, so keep this within thecolouryou are replacing. You can use the top menu bar to adjust how the tool works, including the brush size and shape, how often it samples the area and the tolerance of the sample colour.
