Rainbows are so amazing! That is a really lovely one! I take pictures of rainbows when I can and I have a couple of prisms around the house. I loved when we used spectroscopy in Chemistry. Yeah, there may not be a pot a gold at the end but their beauty is gift enough.
I also have lots of pictures of rainbows...Gotta love 'em. I have multiple crystals hanging in my South bay window and when the sun hits them the rainbows dance around my living room and kitchen. Love it !!
That is a beauty, Charles
