No Selective Coloring! - Photoshop CS2

1. Lets start out with a hue/saturation layer. I upped the saturation to 20 to make the colors pop out more.

2. Now make a Channel Mixer layer and put in the following settings.
RED:
+200/ - 135 / +10
GREEN:
+10 / +95 / +10
BLUE:
0 / 0 / +100

3. Lets make another Channel Mixer layer and set it to "Soft Light" and lower the opacity to about 60%. Now put in the following settings
RED:
+200 / +200 / 0 Set the constant to +200 also
GREEN:
-105 / +200 / -25 Set the constant to -10
BLUE:
Set everything (Including the constant) to +200

Now you can leave everything as is or do the rest of the steps...The last two steps can make your image very pink or very red so it doesnt work with most images.

4. Open up the Channel Mixer again...
RED:
+100 / 0 / 0
GREEN:
0 / +100 / 0
BLUE:
+200 / 0 / +200

5. More Channel Mixer :]
RED:
+70 / + 80 / + 30
GREEN:
0 / +200 / 0
BLUE:
- 100 / +200 / +110
Make the constant -40
And youre done.
