There are many different styles of yard fence on the market in different colors; but there are reasons why black fence mesh is best to use in gardens. 

Black fence mesh tricks the eye and blends in better to surroundings than any other color. Black fence mesh allows the eye to skip over the fence, making it an appealing choice for homeowners who may have close-by neighbors. 

The only issue with black fencing is that white-tailed deer cannot see the color well like humans can, especially in the daytime with their poor vision (20/100). Therefore, fence installers will want to add white deer flags to the fencing to tell deer to stop before hitting a structure. 

Every style of fence, and color, serves it's purpose; but for deer fencing, black is best.
