There Was an Incredibly Rare All-Red Rainbow in England
It wasn’t long ago that DOUBLE RAINBOWS were blowing our minds. Now, something even rarer has happened: A monochromatic, “all-red” rainbow stretched across the sky in Birmingham, England earlier this month.
According to Wikipedia, it’s just like a normal rainbow, but a monochrome rainbow requires the sun to be close to the horizon . . . so near sunrise or sunset.
