Starting Google Chrome leads to altered display colours – why? When I start Google Chrome (seen from 38.0.2125.111 to 42.0.2311.135 (64-bit)) on my 15" Mid-2010 MBP (NVIDIA GeForce GT 330M) on OS X Yosemite (10.10 to 10.10.3) the display often (not just the displayed browser) changes to a much cooler colour, as if I had set a different colour profile. (The colour profile in the settings remained the same) When I shut down Chrome, everything looks as expected again. What's the reason and how can I prevent this behaviour?

Update: GFX shows that when starting Chrome the graphics switch to the discrete graphic card. When I disable this, nothing changes anymore. Turning off the discrete graphics might circumvent the problem, but it is no solution.
Have you tried resetting the SMC?


Shutdown your Mac  
Connect the power cable  
Press and hold the
LEFT Alt + Ctrl + Shift keys  
While still holding the keys above, press the power button


Besides that, could you check what color profiles you have installed and report back? Removing faulty profiles and rebooting might help solve your issue as well.


Open Finder
Press Cmd + Shift + G
Type /Library/ColorSync/Profiles/Displays and press Go


Update: installing a tool that prevents graphic card switching could likely help you as well, though I'd keep that as a fallback option. GFX does a great job at that.
