Case study: How to obtain perfect greyness with TeX?

This question makes absolutely no sense to me. I left a comment asking for clarification. On MathOverflow, I would vote to close with little hesitation.

What's our convention going to be here? How long should I wait before voting-to-close?

To be clear (just in case that question does make sense to someone), I'm asking about the case where the question, as far as I can see, is so vague or contentless as to be impossible to even know where to begin (the one answer so far starts with "I guess you mean ..."). To make it into a proper question would involve completely rewriting it so there's nothing really lost in closing it and the person asking it again more clearly.
