Yeah, black and white are not colours at all...regarding the colour spectrum, we could go into talking about colour temeratures in Kelvin, if you really wanted to.
Some other points...
there is no such colour as "Flesh Coloured", who's "Flesh colour" are we talking about?
When you say the letter "H", it starts with an "A", not an "H"...as in "ay-ch", not "hay-ch".
When referring to somethings small size and gesticulating with your hands, it is not, "this small" its "this big". (no sniggering in the back
)
If you want a truly white finish on your marker, it can be powder coated I think.
Mind you...there is a DM4 in teh classifides at teh moment with a really white gloss finish on it, not sure how that was done.
