Cornflower, Cerulean, Prussian...

Tonight, the sky was full of clouds and heavy with moisture - not rain, but humidity. And it was a shade of blue I have never seen in the sky - so opaque, so thick and heavy. But not gray, or slate, or pewter. Not bright, or clear, or sky blue. It was the dark, pure blue of Caribbean water at twilight. Looking up, I felt as if I were in fact under water. It was amazing to see that color in the sky; to know it was in part due to the moisture suspended up there; to see the weight of the sky itself in that shade of blue - that neverending sea of dark, cerulean blue sky.
