It would seem that making the balloons in bright pink or neon
color might be a better choice instead of white.


White is the highest visibility color for a broad range of lighting
conditions. There are colors that are slightly better in bright light,
some slightly better in dim light, but across the range no other color
maintains reflectivity as well as white.

It could also just be the cheapest. White colored materials are often just
the absence of color pigments.
