I would say the crayfish are....um......crayfish colored. Not sure what you mean but they aren't red or light colored. Just the plain old brown color.

As for spots, that's just not a good question to ask but I will say just look for good structure and baitfish and in general you will find what you are looking for in walleye, pike, and muskie.

Bucktails and topwater are usually two of the best choices for lures though.

Good luck,
