Well, I pretty much just said so, though not using that specific
example. It is white and twice as bright as rgb < 1, 1, 1>. Your monitor
can only display colors with a limitedd range of brightness and most
file formats only store percentages of maximum brightness rather than
absolute brightness, so the colors are clipped at output. There is no
difference in the final output between a color that the camera saw as <
2, 7, 1> and one that was only < 1, 1, 1>.
