We have the ability to produce half & half blades but don't have any now.
Sounds like a good pattern, though. You should make some up yourself and
give them a try.

What I recommend you do is buy a blue permanent ink, felt-tip pen and trick
out a few of your chrome or nickel blades. I've used a red Sharpie on our
nickel blades, and most people can't tell the difference between the shiny,
red blades I make by hand and the more expensive powder-coated ones. The
reflective red (or in your case, blue) finish will be just as effective in
the water. The color is easily touched up after an encounter with a fish,
rock, or wood scratches the in, and you can remove it and change your
pattern easily if you decide to try a different color or pattern.

Modifying large, white willowleaf blades by adding chartreuse spots, black
ribs, eyes and red gill slits is a trick that one of our Prostaff uses
frequently for Kentucky Lake smallmouth. He adds the details to the convex
side of the blade, so as the blade twirls it produces a strobe effect.
