Question

could anybody told me why Paper is always white and why always 'word' wrote in black in books(valid answer please) ​

Answer 1

Explanation:

It is because making the paper black or any other colour increases its production cost (as they will have to buy additional ink.)

and black is used for writing because white and black are contrasting colours and thus easily seen..

Answer 2

Answer:

Black is a color which results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and gray.

It Looks More Visible Than Any Other Color Combination..
