Had to re-read this statement about secondary rainbows being reversed, several times, because the author's color description of the "reversal" still matched the first rainbow's order of hues. I'm not math or physics minded, and already being overwhelmed by those complex details, I thought I must be terrible in English comprehension, as well. My reason for even attempting to read this article was to find out why the color blue in a rainbow begins as light blue before transitioning to darker indigo....which becomes a lighter purple, as violet. I wanted to transpose "the color wheel" mixing of primary colors to understand, without taking into account that the bending of light is not the same as if mixing paint. I'm gonna Google Search the angle from the "Light Color Wheel" to see if Sunlight is the same as Computer Screen Light...which it's probably not. I just want to know what causes a Rainbow blue to transition from light to dark, then to light purple. If I had super vision, would the light purple of violet change to a dark purple. However, my mind has not developed neural synapses to comprehend these answers. I wish!
