Questions people ask
Why does red writing disappear under a red sheet?
Through red plastic, red and orange writing looks the same color as the paper, so it seems to vanish, while black text stays dark. Red Sheet does the same to the page on your screen.
Can I change how dark the sheet is?
Yes. The sheet’s darkness can be changed in the app.
