Thing is, it sounds to me like those companies are actively capitalizing on the familiarity of the RAF roundel. Most archery targets, at least, DON'T have that order of colors. Most have a yellow center, followed by red, blue, black and white:
Most targets for firearms are even simpler than that, with a dark center (black, gray, green, red, etc) and white outer ring (both sections are further subdivided by other ring).
So if they were "just" using a target design, why are they using one that is clearly patterned off the RAF roundel?
