Few times, during last months there is display color problem. Display is not physically broken. It displays colors properly - when no requirement for accurate color reproduring, like image processing.
When problem appears, some colors in the normal palette are displayed wrongly. Usually hues of green are totally lost. And bright blueish and shades of grey - have strange color cast. Same applies with skin tones, those are looking like pink shades. Restarting of the laptop, solves problem.
The problem could be (?) related to the Intel display adapter /video drivers. I updated drivers, and the usage of laptop will tell - does it help to cure the problem.
