Just so. Even for graphics, it's not a huge problem to accomodate a
"fuzzy" match of HSV color characteristics.

It's also been on my mind that a raster image is a special case of an
undirected graph, and *that* is interesting. It gets me thinking on
how I'd approach a flood algorithm aimed at an arbitrarily complex
N-connected graph. A raster is a nice way to visualize how it works in
a limited space.
