But here's a different kind of photo search. On this website, there's a blank canvas. The searcher adds colors, and the website responds by providing photos that most closely match those colors. I'm not sure I would ever have a use for this (especially since the images can be rather expensive--it's a paid service), but it was fun just to try it out.
The photo here is not from the search. It's one of my own, (I'm not going to post a photo that isn't creative commons, isn't in the public domain and doesn't belong to me). It's an example, however, of what the search might turn up if one were to click on green, pink and pale yellow (each search results in many choices, not just one image).
Try it. It's fun!
