/* The red-green-blue colors here are a bit of a compromise:
 * I asked a color picker for a three-color scheme and rotated the
 * colors until the deuteranopy simulation showed three hues that looked
 * relatively distinct, and which the normal-vision display showed as
 * shades of green, red, and blue:  BBFF6D, FF6DBB, and 6DFBBFF.
 * 
 * I then used an HSL calculator to reduce the saturation to 50% for
 * the red and green, and to 25% for the blue (on the grounds that 
 * notKnown is naturally less assertive than valid/invalid, and might as
 * well be less vivid).  Works OK for deuteronapy and protanopy, but
 * the green and glue are too similar for tritanopy.  That's very rare,
 * but let's try taking the brightnes of blue down to 90%.  No, 
 * hard to distinguish from the red, for deuteranopes.  So take it
 * back up to 95%, and reduce the saturation to 15%.  Now it's hard
 * to distinguish the blue from the gray.  So take the gray back up to
 * #EEEEEE from #DDD.  Seems to work, in the sense of providing
 * more or less distinguishable tones for normal vision and (as far as
 * I can tell from the simulations at vischeck.com [thanks, fellows!])
 * for deuteranope, protanope, and tritanope vision.
 *
 * However, the green and pink were very intense, and attempts to 
 * desaturate them failed (made it hard to distinguish other things).
 * So I started over with the color picker from colorjack, choosing
 * split-complentary set of three colors which worked reasonably well
 * with all vision types.  This time, instead of assuming only hue 
 * mattered, I pushed the selector points toward the center of the 
 * color circle, where things desaturate to white, so as to get less
 * intense and ugly colors.  (This experience also explained why the
 * earlier choose-hue-then-desaturate approach did not work:  when
 * you're that close in to the center, it's easy to get tones which are
 * not distinct for all vision types.)
