I need to get the RGB for a pixel that is in an image. Under Windows this is easy but is there a way to do this on Mac OS X?

I usually use DigitalColor Meter (in Utilities). As long as it's open, it gives you the RGB values of the pixel below your mouse cursor.

The only drawback is that the new Lion Digital Color Meter won't give you hex values. The one in Snow Leopard did. – user9290 Sep 19 '11 at 19:41
@Wheat you can change it to show hex under ViewShow values ashexadecimal – koiyu Nov 10 '11 at 13:12
@koiyu Yes, but you can't set that as the default AFAIK. Really bugs me! – daviesgeek Jul 8 '12 at 22:15
Anyone know what the difference is between "native" values and "generic" RGB? They are different. I noticed that if I use native colors, they look different on the iOS simulator. Generic seems to be closer. – n13 Jul 30 '15 at 12:42

Use the built-in app /Applications/Utilities/DigitalColor Meter. Place your mouse pointer over the pixel you want the color of, and DigitalColor Meter will show the RGB values.

I use SpotColor (recently renamed to Hues, more info here)

and HexPicker (which currently has a slight issue with Lion still)

ColorSnapper is the best. $4.99 on the Mac App Store.

Just take a look at the demo video and you'll see what I mean.

I have started relying on the Digital Color Picker plug in to extend the Mac OS X color palette. It's made by Wade from Panic.
