Is there any way to select all pixels on the current layer that match a specific color value exactly?

My first instinct is Select > Color Range..., but I cannot determine how to input a specific pixel color by value, in order to select pixels that match that, and that only.

FYI - if you're used to Illustrator's "Select Same Fill Color" or "Select Same Stroke Color" function - there's not an exact comparison in Photoshop because of raster graphics app vs vector graphics app. –  Joel Glovier Sep 8 '11 at 12:56

I don't think this is a photography question... –  John Cavan Sep 8 '11 at 13:52
    
@John Cavan: Perhaps...but photography-related? This definitely seems to be the most popular of the SE sites for Photoshop questions. –  Unsigned Sep 8 '11 at 22:20
    
@Unsigned Code Labs - There's a Stack site in Beta that I think is better suited to this: graphicdesign.stackexchange.com –  John Cavan Sep 8 '11 at 23:55
    
@John Cavan: Ah, I hadn't seen that one. Haven't really looked at the Beta sites. –  Unsigned Sep 9 '11 at 1:50

You can use the Magic Wand Tool with the following setting:

Tolerance: 0
Anti-alias: unchecked
Contiguous: unchecked
Sample All Layers: *checked or unchecked* (See below)

The Magic Wand Tool also uses the "Sample Size" settings from the Eye Dropper tool, so you will have to switch to that tool and make sure it is set to "Point Sample" before using the Magic Wand Tool. Otherwise you could end up selecting more colors than you intended.

To select a color by value, the easist way is probably to make a new layer and fill some part of it with the color you wish to select, and then use the Magic Wand tool (set to sample all layers) and click on your color patch on the new layer.

IMHO Select > Color Range is the way to go (fast and, I dare say, most semantically correct).

While you are in the aforementioned window, click your eyedropper tool on the little squares (foreground color and background color) in the COLOR panel (usually top right) to sample a color you previously determined in HSB, RGB, LAB or CMYK mode (or simply picked from the palette).

edit - I was about to forget: in Select > Color Range uncheck localized color clusters and set fuzziness to 0 (although you probably figured it out) to select exactly that color over your whole image.
