Thanks a lot. Precisely what I wanted to know.

what i meant was due to refraction the letters will appear raised, like the bottom of a swimming pool does and due to different wavelength of the colours, they appear to be raised at different heights... I wanted to know where the color black lies in this scale.

suppose one keeps a glass slab over a paper containing various colored letters, i kno the order of the height according to VIBGYOR, but what would happen if one of the letters is black? Will it be raised the maximum or minimum?
