Blue Butterfly Thoughts

Blue Butterfly by Wayne Stratz with the row homes of Lansdale, PA
When I go about creating a blue wing, I walk to my tower of glass, go to the blues and choose one, two, or in this case three that delight my eye.

When a butterfly creates a blue wing, it requires a bit more precision. Scales grow forth, each one from an individual cell and thus a colorless membrane is covered. To get blue light to reach my eyes, the wavelength of light entering my eye must be in the range from 400 to 480 nm. The slits in the scales of the Blue Morpho are 200 nm apart. One inch contains 25,400,000 nm. Like I said, I don't need that precision because the glass already appears blue.

Now if I actually worked from scratch, some cobolt or copper would come in handy to make glass blue.
