Question

why paper is white in colour​

Answer 2

hey!!

they are because the printing on them is limited. To make a fine white paper, the mill puts the wood through a chemical solvent process, which separates and discards the lignin. Pure cellulose is white, and the paper made from it will be white and will resist yellowing.
