If you were trying to describe a pink, white and grey space rock, and you were being paid by the word, this is how you would probably do it:
...There were pinkish streaks among the rock, and it seemed that some of the chromatic tint from the atmosphere owed its origin to these. There were a number of white veins in the rock, which bore some kind of resemblance to marble, but the majority of it was grey. It gave an over-all impression of greyness streaked with pink and white, rather than an over-all impression of whiteness tinged with grey and pink, or an over-all impression of pink streaked with grey and white.
Greyness was the dominant background shade; neither black nor white, but something midway between the two. It was a light rather than a dark grey, yet could never have been so light that it might be mistaken for an off white.
