Lines and Colors is published on WordPress.
The template is a variation of the TwentyTwelve theme that I’ve hacked a bit.
The Lines and Colors heading was created using Gothic Light and Gothic Book, on a background crop of Clouds, by John Constable (on Google Art Project, original is in the National Gallery of Victoria).
Headings and body copy are Open Sans.
