Sec. 31.83  Conspicuity.

    The exterior surface of the envelope must be of a contrasting color 
or colors so that it will be conspicuous during operation. However, 
multicolored banners or streamers are acceptable if it can be shown that 
they are large enough, and there are enough of them of contrasting 
color, to make the balloon conspicuous during flight.
