Have some rocks. As always, click on the image for a full-size high-res version. First, a beautiful flat piece of sandstone from the beach at Amble (and second, the other side of the same piece):
And thirdly, the beach at Druridge Bay has trails of glittering black swirled into the yellow sand, from smashed seacoal. Here’s a closeup of the contrast between them, to prove that sand is never just yellow any more than sea is just blue.
Here’s the first sandstone image, turned into a monochrome transparent overlay, and some green alien space rocks as a quick & dirty example.
And as a special bonus, here’s a pattern made using two colours from the Small Tortoiseshell palette I posted last week!
As always, if you find these useful, please consider becoming a patron – even a few dollars a week will keep me in bus tickets and camera battery!
