Man that mother of pearl surface of shells is just about the most beautiful color display in all of nature. Love the fact that there are countless variations on the rainbow in nature, with some being pale and white, and others being bold... Recently discovered that the gray dove feathers hold rainbows in them and even the black raven feathers hold rainbows in them.
Isnt it just so nice and nature so amazing I did not know that about the bed feathers that is so cool
