RE: Color-changing roof tiles can absorb, reflect heat with the seasons
The problem I had with paint pigments changing colors was "perceived buyer resistance" to telling freinds directions to their house ... "It's the light blue house on the right, unless it's between 70 and 80 degrees, in which case it's yellow, except in Winter it'll be dark green" ... keep up the work guys
