"The light that travels from the Sun to the
Earth contains every color there is. But the Earth's air lets the
blue light shine through the best. Sometimes when the air is very
wet after it rains, it makes a rainbow with all the colors. At sunset,
red light can shine through as well."

Where in the rainbow is the purple?
Light from the sun is white. What direction is the light travelling
when it appears blue?
What direction is it travelling when it appears reddish (like at sunrise
or set)?
How many errors can you find in Parade's answer to "Why is the sky
blue?"?
