Question

Using light coloured walls require less lighting compared to dark colour walls?
a) True b) False c) Cannot be said

Answer 1

a. yes it true that using light coloured walls require less lighting

Answer 2

The given statement in the question is TRUE (option a).

• Walls that are light-colored can return back the most amount of light that strikes its surface.
• Dark-colored walls are unable to do so because they absorb some wavelength color and reflect back very few parts of light that strike them.
• White walls, for example, require very little illumination in the space since they reflect all wavelength colors making the reflected light white. This is a light color and does not require more artificial lighting.
• As a result, light-colored walls require less lighting because the light is already there owing to hue, but dark-colored walls absorb all wavelengths, making the room darker and necessitating more lighting.
• Therefore the statement is true.
