Why are oranges always orange?

"there orange"

I believe it has to do with something to the effects of, they are chemically blue but the human eye registers them as orange.... There where other example given but this is the most talked about one.

If anyone is curious... I found it and the answers is: Yes, oranges are really blue. The color we see any object, is the color that is not absorbed by the object. It is the color that it reflects ( in essence rejects) The color we see is not truly a part of the object, any more than an object that we see in a mirror is part of the mirror. The true color is the color the object absorbs and is the contrast of the color seen. Therefore oranges are blue (acttally bluish green :)) Grass is not green it is orange etc etc...
