Litmus paper usually turns either blue or pink (sometimes red) which indicates whether the chemical is an acid or a base. If the paper turns blue it is a base. If pink or red it is an acid.
Seeing red dots could be a sign of eye strain, dry eyes, or retinal issues. White dots could indicate a condition like keratoconus, eye floaters, or a retinal detachment. It's important to see an eye doctor for a proper evaluation and diagnosis.
It appears to be red if a lot of hydrogen ions is removed by a higher concentration of base added
Tea is acidic. Litmus will turn pink in tea.
The cost of making paper depends on the type and quality of the paper as well as the cost of the specific dyes used. Pink, or red, paper can be either more expensive to make than blue or less depending on which specific dye is used and the type, material and thickness of the paper being produced.
