I have an iMac and a second display - an LG 24" panel.
Using any colour picker (eg Digital Color Meter) on exactly the same colour gives a different result depending on which screen I pick the colour from.
As an example - on a web page, the body colour is defined as
On the iMac's display, the colour picker gives me the expected value of
#c00202, but on my other display, I get a different value - in this case
#bc0007. If I change the display profile. I get a different value.
I get what's going on, but is there any way of just making the colour picker return the defined colour - it seems crazy that I'll get a different value depending on which screen I'm using.
