The only truly silly papercrete questions are the ones that don't get
asked. Once they're asked, they magically transform into good
questions. Don't believe me? Check the papercreters glossary in the
files section.
The change in color should certainly make a difference. Whether or
not it's "huge" is a matter of perspective. I know roof shingle
color in traditional structures can change attic temperatures 30 deg
or more in many cases. The less venting in the attic the more impact
shingle color has. In Mikey's case, a container with effectively
zero ventilation and one of the highest thermally conductive
wall/roof materials out there (metal), the change in color will
probably have the maximum impact a color change can have.
Here's an interesting study about roof shingle color:
