is there a way to set black and white as the default for the system, with Ratio Pro? eg then use the wallpapering icon to tun on colour for individual apps like the camera?
At the moment, it works in the opposite way. The phone is too saturated and I have turned off all the colour in ratio settings. However, there is a flash of colour when launching an app, switching between apps or using the system menus like from the top of the screen.
On my Pixel 2XL, I find the colours are way too saturated with Ratio Pro and to the point that I find it uncomfortable to use my phone (I guess that is ultimately the point of me using Ratio but still!)
