    I read a lot of that thread and was amazed such a simple question could become so confusing. So I decided to take manners into my owh hands. It's 2 amish here now, and I took a grapefuit(I don't have any oranges right now) and turned out the light . It became invisible smiles

    Io ...

    Page 1: No problem;

    Page 2: No way.

    Is the URL correct?

    Take care

    and the fun thing is, it's 'only' a matter of definition:
    what is colour?

    - the wavelengths in the array of light?
    then the orange in the dark is not orange, since there is no light.

    - the subjective perception of the light?
    then the orange in the dark is not orange, since it cannot be percieved.

    - a property of the surface which makes it absorb certain wavelengths of light.
    then the orange still is orange.

    - there mayy be other options but the three most serious contestanst are these

    I vote for the second option.

    In order to have a sense of consistency in the universe, we describe objects by attributing properties that are based on what we suppose an average person would percieve under normal circumstances. The average person would be sighted, and normal circumstances would include light. That's why people would describe the orange as being orange even when it isn't observed as orange in that particular situation.

    I'll just call it potential-orange.
