Color Help for Geeks: How to Tell Cadet Blue from Gull Gray

As someone who has a much better systemizing faculty than color-perceiving faculty (I'm red-green color blind, which does haveits advantages), I admit to having had some trouble synchronizing my names for certain hues with everyone else's names for them. So I'm a big fan of this online color-naming application that some nice Web developer has opened up to the world, including us color dissenters. The app lets you pick any of 17 million color combos from an 8-bit color wheel, like the ones used in graphics programs, and then tells you which of 1,500 esoteric names applies. If you're curious, cadet blue is 9EACC2, while gull gray is right next door at 9BA5B5.
