1. Color Replacement Tool
The Tool is located on your
toolbar, and it looks like this:
In order to find this tool, click and hold down on the Brush Tool.
I have chosen a simple photograph of red daisy for this tutorial. To start out, I’d recommend choosing a photograph without too many similar colors. The more complicated the photograph, the more complicated this process will be. Once you have mastered this tutorial, feel free to work on any photograph you’d like!
We are going to change the color of the red daisy. In order to use this tool, you’re going to need to set your foreground color to the color you want your daisy's petals to be. Take a look at the bottom of your toolbar, and you’ll see two overlapping squares – one black and one white. Click on the top square.
You’ll see a new window pop up, allowing you to choose any color you’d like. Once you have chosen it, and click ‘Ok’.
Take a look at the top of your screen. You’ll see options saying Mode, Limits and Tolerance. You’ll also see your brush options, such as size and hardness.
A useful tip: if you want to change the size of your brush easily, use the left and right bracket keys. The left bracket key ( [ ) will make your brush smaller, while the right bracket key ( ] ) will make your brush larger. Want to easily change the hardness? Simply press the same two brackets while holding down the shift key. The left bracket will make the edges softer while the right bracket will make them harder.
The Mode should be set to Color, since you’re only trying to change the color. Your Limits should be set to Contiguous, and your Tolerance you can play around with, but I have mine set at 40%. This allows me to paint over the yellow edges of the red daisy's petals, yet still remain within the red daisy and not bleed out onto the background.
Now begin to paint on the area of your photograph that you want to be changed
See how they’ve changed to a more mauve color? You can use this tool on anything in your photograph that you want to change, and by changing the Mode to Hue, Saturation or Luminosity, you can change all of those aspects of the photograph as well.
