Nothing like real data ......I also took measurements (EV) with spot meter
at noon in a very clear, sunny Los Angeles. White T shirt and black knit
shirt.
Full Sun Medium Shade 5 Ft inside House
White Shirt 18.0
Black Shirt 13.2 9.4 7.0
Result: 8.5 stops between bright white in full sun versus very non
reflecting black in medium shade.
