I was once trying to match a colour from a logo in a PDF. Using the included 'DigitalColor Meter' that ships with Mac OS X.

When displayed on the Macbook Pro screen it registered as one colour. On my Dell monitor it registered as something slightly different. When I used that the colour in CSS, the colour rendered differently to the original image, and DigitalColor Meter reported that there were different values between different browsers (Chrome and Safari) and different screens.

And none of these visually matched the colour of the original image on either monitor.

Not sure if it was gamma adjustment, colour calibration, drivers, graphics cards... in the end I gave up and did the best I could.

I'm not sure why you'd want to buy a utility that replicates already built-in software, but one great value-add point would be to disentangle all of this nonsense.

I was going to say exactly this. Does anybody with a good understanding of monitor colors know why this happens & possibly how to deal with it?

It's complicated :) but I try to explain: On OSX you can use AppKit and related frameworks to create an app or browser like Safari. All colors are subject to Color Management and are converted to your Display profile.

So Safari takes CSS color values assumes they are in sRGB and converts them to your display profile. For Chrome and Firefox this is a different story. They use their own render engine so no conversion takes place here. This is the reason why colors differ between Safari and Chrome/Firefox.

ColorSnapper recognizes if you pick from a Color Managed App and converts the color back to sRGB. There might be a slight difference because of rounding issues, but it's the best you can get.

As for picking from PDFs or Adobe Photoshop: this depends on the app you are using (Preview App, Adobe Reader etc.) and if they have their own Color Management, but that is a little beyond this post. We will soon write a blog post about that on http://colorsnapper.com

Thanks for the explanation. I love focused products like this with a borderline insane attention to detail. I'm giving the free trial a shot right now.

If you want a free color picker for OS X see Sip: https://itunes.apple.com/ca/app/sip/id507257563?mt=12

There's a paid upgrade version as well. http://theolabrothers.com/pro.html

If you want a free colour picker for OS X, it comes with one included ("DigitalColor Meter").

I also like ColorPicker for Sublime Text: https://github.com/weslly/ColorPicker

The original is one of my most used Mac apps: being able to pick any colour from any program with one keystroke and a click, then to paste the hex into my text editor with one more keystroke has been invaluable. No idea whether version 2 is worth paying for again, but a quick scan of the site makes it look good.

The new version supports some cool new features. eg.: Hi-Precision Mode: When activated it increases zoom and slows down your mouse so you can pick any retina pixel on screen - currently no other picker offers this.

Very nice color picker, especially thanks to its magnifier tool.

The 'Android' format is not very useful though :

It outputs in the 'Color.argb(x,y,z)' format which is almost never used in Android development but does not support the infinitely more useful android xml format : <color name="color_name">#FF112233</color> .

kind of windows equivalent: http://www.nattyware.com/pixie.php

If there's a Linux one, I'd be interested

Never mind, found gpick

Wow, gpick is much better than gcolor2, which I was using before. Thanks!

Still using Fireworks and its color picker tool. What a great tool and what a shame Adobe is shutting it down.

I read this as 'ColonSnapper'. I might be the only one.
