Answer 1

The house reflects mostly blue light

Answer 2

Answer: The house reflects mostly blue light.

Explanation: The color of an object as seen by our eyes is determined by the color of the light that they reflect.

In case of a blue painted house, all the other colors of white light ( which is a combination of multiple colors) falling on the house are absorbed and only the blue colored light gets reflected back. Hence the house appears to be blue to our eyes.
