A 4th Rule For Fly Color Selection

Postby Karl Klavon » Fri Jan 27, 2017 11:05 am

Here is a 4th Rule for Color Selection: Choose a fly that is as close to the color of the water you are fishing as you can make it.

The reason that anything is the color it appears to be is because that is the color of the light that is being reflected back into our eyes to see. All of the other colors that light is made up of (all the colors of the rainbow and more) are being absorbed by the object in question, except for the color that we are seeing. So choosing a fly the same color as the water will reflect more of the available light back in to the fish’s eyes, as well as ours.

Here is a link showing various colors of fishing lures as they appear above the water, and as they appear in clear/blue, green, and red/brown colored waters. The text is well worth reading but pay particular attention to which colors of spinner blades are most visible to you in the water colors shown, as the text contradicts its self in places. Here is the link: http://www.mepps.com/fishing-article/color-technology-what-you-see-is-not-what-you-get/77

One of the things you may happen to notice is that the metallic colors (silver, gold, and purple and yellow to a somewhat lesser extent) and black and white are the most consistently visible spinner blade “colors” in all of the various different colored waters. “Colors” is in quotes here because black and white are not true colors. White light is made up of all the colors of the rainbow, while black is the absence of light, and a black appearing object will absorb any color of light that strikes it, while white reflects all colors of light except black.

Contradictions Noted: “Chartreuse is a terrific color in clear blue water, even at great depth. However, in green water, it is almost invisible.” Looking at the clear blue water photo, chartreuse is one of the dullest appearing colors, while in green colored water photo chartreuse is among one of the brightest lure colors. While it is true that chartreuse is one of the brightest colors at great depth, that is because it is usually a Fluorescent color and does not shift color or fade with increasing depth and distance, like standard colors do. All of the Fl-colors share this brighter with distance and depth characteristic advantage over the standard colors. And either or both visible and UV light can excite a Fl-color.
