Indirect relation to the color idea: My old 24x48 shop in Maryland - years
ago I had the rusty steel roof painted dark green, thinking it would look
nice. It did, but the attic storage space quickly found a nickname of 'the
sauna'. Then, not as many years ago, the same painter was hired again to
paint it, this time white. The first hot summer day was remarkable - the
attic space was almost same temperature as the downstairs. It stayed that
way for several years, incredibly pleasant to spend time up there in summer
sorting through boxes of parts. Gradually the white got dirty and stained,
and the heat started to come back to the attic space. Bright white WORKS
excellently, in my experience.
