Re: Need Input on a new Fly i tied
You're right about colors being visible in water. Red is at the top of the visible light spectrum, purple (violet) is at the bottom. So as light penetrates the water, the shorter wavelength light, like violet, will go off last and the longer wavelength light, like red, will go off first. When I learned the light spectrum back in high school, they used a person's name to help you remember the order of the colors: "Roy G. Biv". Strange last name, I know, but it stuck with me. Here's the order
Roy G Biv = Red / Orange / Yellow / Green / Blue / Indigo / Violet.
Here's a little more detail:
Color Wavelength Frequency
violet 380–450 nm 668–789 THz
indigo 420–450 nm 668–714 THz
blue 450–495 nm 606–668 THz
green 495–570 nm 526–606 THz
yellow 570–590 nm 508–526 THz
orange 590–620 nm 484–508 THz
red 620–750 nm 400–484 THz
I've never fished at 50', but it might be interesting to run a little experiment to see what colors stopped working for you as you go deeper; maybe try yellow, blue and purple and see what color hooks more fish at what depth.
Probably a lot less fun than just fishing, but it might be an interesting thing to demonstrate.
