Can I custom book app’s font and background color for eye health?
A: Android book app maker enable you to setup default font and background color for the output book apps. The output book apps also allow its readers to adjust the font and background color from its default color.
For eye’s health, we shouldn’t adjust the color too bright (dazzling) or dullness which also does not benefit our eyes. When your eye feel tired, you should try your best to make it relax. Anyway, you can select green or yellow,
etc to accommodate.
Launch Android book app maker. Try to create a new book and add chapters for it, then click icon "Config", then turn to the tab "Display Config", and then begin setup
default font and background color to the best healthy for eyes.
