Replace Colors in Photoshop

First thing you need to do is open your image in Photoshop.

Simply go to the Adjustment Panel at the right-hand side of your Photoshop screen (if it’s not there, then go to Window » Adjustments), and select the Channel Mixer option.

Next, keeping the Channel Mixer layer selected in the Layers panel, you should press Ctrl + I to inverse the color of the layer mask.

The Layers Panel should now look like this:

Now you need to find the areas where you want to replace the colors. Create a selection on those areas with the Quick Selection Tool.

After making the selection, go ahead and select the Brush Tool from the toolbar. Set the color to white, and brush over the selected areas. You will not see any change on the image, but you will be able to see the effect in the layer mask on the Channel Mixer layer.

Once you are done with the brush, go ahead and look for the Output Channel dropdown in the Chanel Mixer settings. By default, it is set to ‘Red’.

You will find three sliders for Red, Green, and Blue. Adjust the sliders using the following settings:

Red: 0%
Green: 100%
Blue: 0%

In the next step, you should set the Blue color in the Output Levels dropdown and use the following settings for the three sliders:

Red: 0%
Green: 100%
Blue: 0%

Lastly, use the brush tool to clean up any leftover colors for a perfect result.
