Acrylic and urethane based white paints have 93% blackbody radiation efficiency at room temperature (meaning the term "black body" does not always correspond to the visually perceived color of an object).
Bijele boje bazirane na akrilu i urethanu na sobnoj temperaturi zrače 93% zračenja crnog tijela (što dokazuje da "crno tijelo" nije nužno crno u vizualnom percipiranju nekog objekta).
