I've been able to in the past use the eyedroper tool to grab colors from browser windows and get the exact coded color if it's a css color. I'm using Photoshop cs5 on a mac with snow leopard. When I try to get any color from a browser window (both safari and firefox) photoshop will shift the color slightly. Anyone have any ideas as to why? Do I have setting that is wrong all of sudden?
The browser may be color managing the values, and so the value on screen might be #fefefe (or #fef0e0 if you have a bluish screen).
As far as we know, Photoshop is not shifting the color values - Photoshop is getting the exact color value from the display buffers.
Is there any way to adjust this? I also have photoshop cs2 on lion that gets the color accurately. They are different displays. Does that make a difference? The one with cs2 is the older Apple lcd cinema display and the other the newer led cinema. Thanks again.
The displays might make a difference.
And Photoshop is getting the color accurately, as far as we know. Photoshop gets exactly what the OS puts on the display -- but that may not be exactly the same as the values you specified on the webpage, because the colors are converted for the display.
One more question. If I use a third party app like xScope to get recoil or reading, it reads exactly the right color from the browser. Why does this app behave as expected and not photoshop? It seems that if the color is coded at #ff0000 it should read as that. Photoshop reads this as as #fe0000. Whereas, xScope reads it at #ff0000. Is there any way to change a display setting or photoshop setting to get this to work?
I don't know. Again, Photoshop is reading the value straight from the OS (which copies the framebuffer so that Photoshop can read it).
And when we test it, we get the exact values we expect from the display.
