With all the rains we've had in San Diego.... I'm out chasing rainbows!!! The sky is so clear it feels like I got new eye glasses!
There are seven colors of the rainbow which can be remembered by just using one key word. This word in ROYGBIV which is an acronym for the seven colors. ROYGBIV stands for Red, Orange, Yellow, Green, Blue, Indigo and Violet. You will notice that each color sits next to a color that is similar to it such as red then orange then yellow. Mixing paint that is red and yellow will give you a n orange color and is one proven way of showing the changes of color in a spectrum.
When it is raining heavily there is less chance that the rainbow will appear because the sunlight has difficulty piercing the heavy rain drops. In mist you will see the rainbow or after a light shower you can see the rainbow too.
