Where is the barrier-free setting of Samsung s20?

Then slide down the X2 time menu in the main interface, click the gear setting in the upper right corner to enter the setting, and then click the display in the display screen to adjust the color of the Samsung S20 system.

You can also edit the daily program through bixby, and let the mobile phone set the display color of the mobile phone to different colors required by the user at different times according to the user's customized instructions. I hope it helps you.
