The colors on my screen are messed up - most everything appears as blue, purple and reds. I can't watch movies on it bc the colors are all wrong. I have an early 2015 retina 12-inch MacBook, version 10.12.6, running on macOS Sierra. Under system preferences, displays, the resolution is set to default. This problem just suddenly occurred for no apparent reason. Please help. Thank-you.

Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time. You may need to do this 2-3 times.
Reset NVRAM/PRAM
Try a SMC reset. The article covers when this is required, but doing this will not affect anything.
Reset SMC
Try setting up another admin user account to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

Thank-you Eric, but unfortunately none of these suggested fixes worked. I systematically went through each step - restarted using command-option-P-R 3 different times, reset NVRAM/PRAM, reset SMC, used another account (same problem with colors being off), and Safe mode. There are no Apple stores in Thailand, so I am not sure what to next.
You are welcome. Try working through the screens in this link. You can get a chat option and an option to find an Apple Authorized Repair Center, if there are any.
