Final answer:
Avoid solid white, solid black, and blue while deer hunting, as these colors can be visible to deer. Instead, wear blaze orange for safety, which is visible to humans but not to deer.
Step-by-step explanation:
When going deer hunting, it is important to choose attire that keeps you safe and increases your chances of a successful hunt. Some colors can be highly visible to deer, which may lead to decreased success. The colors to avoid are solid white, solid black, and blue. Solid white can stand out in the natural environment, especially during times when there's no snow. Solid black isn't typically found in nature and can be noticeable to deer. Blue is to be avoided because deer can see it well; it's also the color of many forms of denim, which is a common clothing material.
Instead, hunters are often advised to wear blaze orange for safety, as deer do not see it as a vibrant color, but it is highly visible to humans, preventing hunting accidents. This does not mean dressing head-to-toe in blaze orange, but rather incorporating enough of the color into one's attire to be visible to other hunters.
