Colours

[poliphilo]

 I looked up from the screen and the sky was violet. It only stayed that way for a few moments- and the it was blue. Or should I say "grey-blue". Ach, the colours of these northern skies are so transitory, so fugitive, so subtle. Also they bleed into one another. At this instant the sky immediately over the hills is a sort of dusty pink which gradually modulates into duck-egg blue the higher your eyes climb. Can I say exactly where pink ends and blue begins? Absolutely not. 

And since I wrote the last paragraph, just moments ago, the pink has modulated into a kind of yellowish-grey- a shade for which I don't have a single word. Maybe "magnolia" would come close.....
