As I go about the landscape, I often see colour compositions perfect for website design and layout.
Indeed, fancy software is available that does just that. But these tools are usually over-specified, and we can so the same sort of things ourselves.
In this example, we might use the paler parts of the sky for our background, the bright blue for links, the serious cloud colour for headings and body text, and the greens and golden colours for text accents, underlines, and decorative motifs.

What I like most about this idea is how it provides a great opportunity for immediate collaboration. “Hey Charles, I would love it if my website could incorporate the colours in the photo that I’m sending.”
The colours will then end up in the CSS for your website. I discuss CSS briefly on my Terminology page.
