Change the colour alloted to the sim card you use.
The background colour of the call screen is the colour alloted to the sim being used.

To change the colour, (I am using Nokia 6.1 with Android 8.1)
Go to network and internet
SIM Cards
Touching the sim card symbol would give you a prompt in which you can change the colour.
Problem Solved!!!!

PS. I too had the same problem. Had the pink colour which was awkward
