I have gotten a picture of a snail that I am allowed to manipulate.  I am trying to change its colors to a famous pink snail.  The snail is originally a brown color snail.  I am trying to select just the shell to change to pink.  I have photoshop CS5 and would like to do this to learn PS better.
I have not figured out how to change the shell's color to pink.  I can sort of get it to hot pink, but I was thinking more of a baby pink.  I must be doing something wrong.  How do I change the color of the shell to a baby pink?
I know I have to put the shell in a new layer, so I won't change everything to that color.
Thanks for any help.

There are number of ways, but quickest would be to use Quick mask mode and paint the selection around house. CTRL+J to copy house to new layer, use variations to color it pink, and finally use Color blend mode to make it more realistic. Hope that helps ;)

Open your mind and share the knowledge!

I'd draw a selection around the part you want to affect with the effect. (And touch up a little with the aforementioned quick mask.)

Then once that selection is how you want it, make a new adjustment layer for Hue/Saturation and check the box for colorize. Then play around with it in preview. The adjustment layer can always be tweaked for color and strength later on.

You can also use the alpha part on that adjustment to remake the selection in order to do a copy merged and paste that output to another layer as a fast way to have a more "tangible" version of the colorized part to work on. Hopefully that makes enough sense.

The snail is a photo.  I want it to be pink with a blue body.  The snail can look toony as those are not realistic colors for a snail.

 here's a "quick and dirty" example using the above suggestions (quick masks and hue and saturation adjustments)  

what's good about this is that it is all "non-destructive" (meaning NO PIXELS WERE HARMED IN THE MAKING OF THIS EFFECT) - if you don't like it, toss out layers and try again
