A rainbow has depth to it, all along the radius refraction angle of 45 degrees. A halo around the moon on vaporous clouds has red and magenta on the outside, the yellow is minor, green and cyan are the inside colors. The lighter area is to the inside. A moon bow is magenta, white, green, and rare.
This double reflection causes the appearance of the secondary rainbow. The colors of the secondary rainbow are lighter than the primary rainbow because the amount of light that escapes the two reflections is more. Also, the secondary rainbow has more surface area in the sky.When you look closely, there is a dark area of the unlit sky present between the primary and secondary rainbow.his means that the color red which appears on the outside for a rainbow, will be visible on the inside with the blue color on the outside of the double rainbow. It is caused by the reflection of the sunlight inside the raindrops. These raindrops appear at the angle of 50Â° to 53Â°.
