There are other colors, but you typically see them in tans or neutral tones. Part of it is that it's a lot easier to see if there's a bee on you when your suit isn’t dark, lol. Another part is that you work in the bright sun, and a light suit helps keep you cool. Finally, some beeks say that bees are attracted to, or even angered by, black. Not sure if thats true, but either way a black suit sounds miserable!
