Another way is to fill a new layer with the colour you want, and set the layer blend mode to Color. I think I would use the previous poster's Hue/Sat adjustment layer method myself though.

Great suggestions so far.
Try also the Tint feature in the Image - Adjust - Black & White, or Layer - New Adjustment Layer - Black & White.
The nice part about using an Adjustment Layer is that you can adjust the color of the tint, opacity of the layer - virtually EVERYTHING - until you get it looking just right.
If you combine either technique with a black and white adjustment layer with the blend mode set to overlay at 20-30% then the image really pops and has more contrast. Try it and you'll love the results.
