I'm pretty sure that the subjective experience of colors is mostly due to a combination of the overlapping ranges of wavelengths our eye's cones respond to (how similar different colors appear to us), and associative recall ("grass green").

Note that subjective perception of color is only loosely related to the actual frequencies of light involved.

Try loading the image of these "red" strawberries into GIMP/Photoshop, and use the color picker to see what color they really are - grey.
