How To: The Color Replacement Tool- Part2

Hello! Welcome to part 2 of the Color Replacement Brush tutorial. Did you all try and recolor something? Well, today I am going to tell you a little bit more about the CRT {color replacement tool}.

Blending Modes

Did you know that there are different blending modes you can use with your CRT? The default is color, but there is also hue, saturation and luminosity. Here is a brief breakdown on the blending modes-

Hue: The Hue blend mode will change only the basic color. It will not change the saturation or brightness of the original color. This mode is great for images where the colors are not very intense and will  produce very subtle changes.

Saturation: The Saturation blend mode changes only the saturation of the original color. The hue and brightness are not affected. This is good for reducing the intensity of a color, or even removing color completely.

Color: Color is the default blend mode and will change both the hue and saturation. The brightness will remain unchanged. This is the blend mode you’ll use most often.

Luminosity: Finally, the Luminosity blend mode will simply match the brightness of the original color to the brightness of the new color. Hue and saturation are unaffected.

Sampling Options

Those three little boxes following the blending modes menu are the sampling options. Sampling options control how Photoshop samples colors in the image. The first box is continuous sampling {most used}. With Continuous selected, Photoshop continually looks for new colors to replace as you drag the CRT around. Any new color the crosshairs pass over becomes the new color to replace. This is the setting works best when there’s a lot of variation in the color of the object.

Next is  Once sampling. Photoshop will only sample the color you initially click on regardless of how many other colors you drag over (as long as you keep your mouse button held down). This option works best if you’re replacing a large area of solid color. You can also try the Once option if you find that Continuous is causing the Color Replacement Tool to bleed into other nearby areas and the Tolerance option doesn’t seem to help.
Lastly, the Background Swatch setting will replace whatever color is currently set as your Background color. This option is rarely used.

One Last Thing

To the right of the sampling boxes are the Limits. The default Limits option is Contiguous. This means that the CRT can only change the color  in the area the crosshairs is touching. It won’t affect the sampled color that is separated from the crosshairs by an area of a different color unless you actually drag the crosshairs into the new area. The opposite of this is Discontiguous, which allows the CRT to replace the color of any pixels that match the sampled color and fall within the circle of the cursor, whether those pixels are in the same area as crosshairs or not.  Also, always keep anti-aliased checked, this will make sure you have smooth edges.

Thanks for coming back! I hope you learned something and that this wasn’t too confusing!
