$\Large\fbox{\color{purple}{ SOLUTION }}$

★ CLOUDS LOOK WHITE ★

CLOUDS ARE AT LOWEST EARTH ATMOSPHERE CONSIST LARGE DUST PARTICLES , WATER VAPOURS SINCE THE SIZE OF PARTICLES ARE LARGE ENOUGH . ALL THE WAVELENGTHS OF COLOUR COMPONENTS OF SUNLIGHT SCATTERED EQUALLY HENCE ALL THE SCATTERED LIGHT COLOUR MERGE GIVE OUT THE SENSATION OF WHITE COLOUR WHICH MAKES THE CLOUD APPEAR WHITE

★ RED IS A DANGER SIGNAL ★

DANGER SIGNAL COLOUR IS RED BECAUSE THE RED LIGHT USED IN SIGNALS HAS THE LARGEST WAVELENGTH AND LEAST SCATTERED BY FOG , DUST PARTICLES, SMOKE PARTICLES, DUE TO THIS RED LIGHT CAN BE SEEN EVEN FROM A LONG DISTANCE

Answer 2

Step-by-step explanation:

When clouds are white (and many are not), “it's because light from the sun is white, a combination of all the colors of the rainbow,” said Michael Kaufman, professor of physics and astronomy at San Jose State University in California. As light moves through the clouds, it is dispersed by water droplets.

Red colour is always used for danger signals, because as red colour is having the longest wavelength, it is the least scattered. So, this signal can be seen from a very long distance.
