Yeah I made an app that told you what color you were looking at. It was intended as an accessibility and/or creative application. There was a little reticle in the middle of the Glass, and whatever was within that reticle, I grabbed the average color (out of around 16 pixels worth of data), and showed on "screen" optionally either the hex value, or an approximate name (e.g. "deep sky blue"). I was working on making it save the hex value when you say something like "Hey Glass, save this color", but I didn't get quite that far before having to move on to other projects. The intention with the latter part would be that a digital artist could be like "I like the color of this flower" and then save that color for later if it inspires them.
