Answer 2

The original sunlight is a mixture of colors.

Step-by-step explanation:

• The sunlight is perceived by our eyes as white because it is a mixture of seven colors - violet, indigo, blue, green, yellow, orange, and red.
• When these colors of light separate from each other and are differentially absorbed and reflected, we can see the different objects in different colors.
• The reason for the differential absorption and reflection is that the different colors have different wavelengths.
• Therefore, the barn looks red because the red light is reflected by the barn and other lights are absorbed, however, the original color of the sunlight is white.
