Chrome 65 for Windows has an endless issue with colors. It just display some of them differently than FF and IE. Even Chrome on MacOS does not have this problem.
See the picture here : Left Chrome, Right Firefox
On the left, the color displayed on Chrome, on the right the color in FF. The color code is (0,187,187) with transparency of 0.7 In Paint, the color looks like the FF one.
I know I can switch chrome://flags/#force-color-profile to sRGB to get the right color back but I cannot do that on my customers' machine.
Thanks for your help.
Actually I found the solution. Chrome is going to read the color configuration file of your windows operating system. Firefox will not do it by default and use a sRGB setting.
So you must go to "Color Management" and change your default settings (see picture).
