Based on your description, I recommend you updating the bios in your system and installing the latest driver provided by the computer manufacturer.
The latest bios and graphics driver are installed on the system. I disabled Microsoft ACPI-Compliant Control Method Battery in Device Manager. This makes the system think it is not running on battery so the colours became ok but the power icon is gone.
I just tried disabling the graphics driver before shutdown/restart and enabling the graphics driver on startup. This fixes the colour but it is inconvenient to keep doing this.
