WebJul 29, 2024 · The primary rainbow is a bright circular bow seen in the sky at an angle of about 42° relative to the horizon. This bow consists of six concentric bows of different colors – the innermost bow is purple, then come the blue, green yellow, and orange ones, and the outermost bow is red. WebIn Fig. 3, the red is at 50.4 degrees and the violet is at 53.4 degrees. (The angle will differ slightly depending on how the wavelength of the color is defined.) Occasionally, a faint secondary rainbow appears outside the primary rainbow. Here, the order of red and violet are reversed in comparison to the sequence in the primary rainbow. sutter health issues
