HELLO FRIENDS,
-----------------------------------------------------------------------------------------------------------------
1>Danger signals are made of red colour because the wavelenth of red light is maximum , and from this reason it scatters less i.e it can be seen by a long distance.(wavelenth^4= 1/ scaterring power)
2>The sky appears to be blue during day time to a person on earth because Blue light is scattered in all directions by the particals of atmosphere since it travels as shorter, smaller waves than other colours.

Best of luck ;)
