: Replace red with black using Photoshop How can I replace all red with black on the image below, using Photoshop, without damaging the image? Thks!

@Annie732

The easiest way. It is easy because there are only two colors. Take the quick wand tool and select all reds. Make background color black. Then ( Ctrl+ backspace). Its done!

Lots of options, and while I do really like Yorik's channel approach which will work for this image, let me offer you what I believe is the easiest and probably best solution, which will work on all images not just yours: Hue/Saturation Adjustment Layer

Hue/Saturation Adjustment Layer, go to Reds, lightness to 0:

Hue/Saturation Adjustment Layer, go to Red, lightness to 0... and then go to Magenta and drop its lightness to 0 too:

Go-Junta has a good generalized answer, but for this specific image:


open the channels palette
delete the red and green channels
set the image mode to greyscale
set the image mode the RGB again (optional)

If you have the choice and can avoid using the magic wand tool, don't use it. It can work well on big images but not so much on smaller ones.

Since you simply want to change the image from red to black, you could simply:


Put that image in GRAYSCALE COLOR MODE
Then use the LEVELS (menu Image > Adjustments > levels)
Then use the black color picker and click on the red area. It will change the light gray to black. You can change the black density or recipe by double clicking first on the black color picker first.




This is a non destructive method and it will also take care of the anti-aliasing.



If the white part of your graphic is actually transparent, you can also simply use a COLOR OVERLAY in the layer style (double click on your layer for options), and select black as color.

You'll be able to change that color as many time as you want and keep the original color too if you want to revert to it.

There are probably half a dozen ways to do it, but a quick one is this:

1) Duplicate the layer the artwork is on.

2) Use the Magic Wand tool to select the area outside the white circle, then hold the Shift key and click inside the puzzle piece to select that area as well.

3) Make sure your background color is set to Black, then hit Cmd (Ctrl on PC)-Delete to fill the selected area with Black.

You'll now have two layers: The original red/white, and the new one which is black/white.

While typing this answer I thought of 3 separate but similar methods to get the same result, so there are many "Correct" answers!
