Camo paint or fabric is intended to hide reflections from shiny stuff under a tree canopy. Back even before the turn of the century, manufacturers of commercial two-way vertical antennas inside fiberglass radomes determined that a light creamy-blue was the color least likely to contrast and stand out against the sky as a background.
White jacketed #18 to #12 stranded wire is hardest for the HOA folks to find against a bright sky. For hiding rigid antenna elements or structure, dull the (aluminum) metal surface with steel wool, then apply a coat of light sky blue latex paint. It's non-conductive and does not smoke, burn, or melt. No, we as consumers generally cannot buy lead based paints any more.
