Question

Why black umbrellas are better than colourfull umbrellas

Answer 1

Colourful umbrellas have glare and they will reflect light from the ground/water back to the user whereas black umbrellas absorbs more heat than any other colour

Answer 2

Answer:

Black can absorb heat.

It was found that umbrellas made of black cloth dried faster than those made of cloth of other colors. ... The black fabric dries faster because black or dark surfaces absorb more heat from the surroundings than lighter surfaces and as a result, the evaporation process is faster.
