When creating screenshots or using similar tools (such as Snipping Tool or Snip & Sketch), the resulting images may have an unnatural orange tint as shown below. This problem started on or around September 5, 2019.
This problem is caused by the Eye Care mode feature of Lenovo Vantage.
Disable Eye Care mode and reset the color temperature in Lenovo Vantage. Currently, there are two different versions of Lenovo Vantage; the solution is slightly different depending on the version of Lenovo Vantage that is installed on your PC.
If you're using Lenovo Vantage version 4: Go to Hardware Settings -> Audio/Visual, then turn off Eye Care Mode and click on the Reset button as shown below.
If you're using Lenovo Vantage version 10: Go to My Device Settings -> Display & Camera. Then click on the Reset button for "Daytime Color Temperature", turn off Eye Care Mode, and uncheck the box about "Schedule eye care mode" as shown below.
