Feature request: total red filter / color lens #3718

Just started using GrapheneOS and was disappointed at not being able to completely turn off green and blue pixels. I have seen friends do this on their devices. It is critical for visual astronomy to avoid green and blue light as it wrecks night vision.

It seems stock Android has some "color lens" accessibility option which does so. (I never used stock Android so i can't confirm this.)

You can set the filter much higher on GrapheneOS than the stock OS, and you shouldn't need more than the maximum. Did you try setting it to the maximum value?

Yes, and am seeing non-red light nonetheless. (i.e. can see multiple colors on the screen)
