Possible mistake in book regarding colour Watch
"A colour wheel can help us to work out which colour(s) are most easily absorbed by an object. A blue object absorbs most strongly in the orange region of the visible spectrum. Orange is called the complementary colour to blue and is opposite blue in the colour wheel. It is the complementary colour that is seen."
Surely, if Orange = complementary colour and complementary colour = is seen, then it should be a orange object and not a blue object. Is this book incorrect as it makes no sense because it says a blue object. Shouldn't a blue object reflect blue?
so it should say: "It is the complementary colour that is absorbed."
Which is stupidly phrased, of course. :P
