Color MashUps

OK, the concept of "mashups" are new to me, but I really like the Color Fields Colr Pickr application.

It is through this particular mashup that I am beginning to understand the power of tags in Flickr.

At a glance, it looks like the color tags are hexcodes. Gosh, I have not used those in awhile! Probably since I got away from hardcoding HTML...does anyone do *that* anymore?!
