Short version: asked how to get a pixel's RGB in Photoshop and rightly pointed out simple pickers. For a few one-off samples inside Photoshop use the Info panel plus persistent Color Samplers (so you can mark points and read exact channel numbers without changing document state). For repeatable or coordinate-based extraction use a small script or a command-line tool so you can get precise values programmatically and avoid human error.

Practical Photoshop workflow (concise): open Window > Info to see numeric readouts; place Color Sampler markers to lock measurements; set the sampler options so you get a single-pixel read or an averaged block depending on needs; choose whether you want the sample from the current layer or from the composite (All Layers). Before recording values for web/CSS, convert a copy to sRGB and ensure the image is in RGB mode so the numbers match browser expectations. Remove samplers when finished.

When you need automation or many samples: Photoshop supports scripting (ExtendScript/UXP) to read ColorSampler values and export RGB/hex lists. For quick batch extraction from files without opening Photoshop, ImageMagick can report pixel colors by coordinate from the command line. These approaches are useful when you must sample dozens or thousands of pixels or embed precise values in a workflow.

References and further reading: Photoshop Info/measurement docs are in Adobe’s help center (see ), and ImageMagick’s site documents command-line extraction options (ImageMagick).

It's been a while since I've used photoshop. But generally speaking, if I need to find the RGB value of a pixel in any graphics package (usually gimp/paint.net/inkscape), I'd zoom right in on the image so I can see the pixel I'm after and use the colour picker tool (looks like a pippette / eye-dropper) to select the pixel.

This action will usually set your active colour (either the foreground or background colour) to the same colour as the pixel you clicked on with the colour picker. Next click on the colour (the one that changed when you used the colour picker) and you'll usually get a popup which shows more detailed info on the properties of the selected colour. (HSV, RGB, and HEX values).

Trust me it sounds much more long winded than it actually is...It only takes a second or two to do, so it is a pretty quick method!

Like I said, I haven't used photoshop in a long while, but the method I've described can be used in most decent photo editing software nowadays and I'd assume that photoshop will be no different!

Alternatively, there are loads of little tools that are freely available that will allow you to view the colours of pixels anywhere on your screen. If you're on windows, there is a little .NET based tool I've been using on my windows PC's called cpix.exe (google it and download it!).
This neat little tool opens a small window which stays above all other windows. Inside the window you'll see RGB details of the pixel currently under the mouse cursor. There's also a magnifier which shows the area around your mouse cursor. You can use it to zoom in on images and examine the colours of individual pixels. Pressing the spacebar will lock cpix to the pixel your mouse is hovering over. You can then make a note of the RGB value and use it in your photo editing software/html page/whatever!

I'm sure there are similar tools available for other platforms!

Anyways, hope this is of some help.
Cheers for now,
Jas.
