"yumm" - the colour of a juicy insect on a bat's radar. As to imaginary colours in general: aren't all visible shades already defined - my computer tells me that it knows "millions of colours" anyway... We just don't happen to have words for them. I once read, the eskimo had many words for snow - quite possibly the would not agree with the stuff being simply white! On the other hand, what we see is just a tiny part of the electromagnetic spectrum. Other species "see" other parts of it - for example, we're missing out on beautiful ultraviolet colours of many flowers! Medical images routinely map normal colours to structures visible only at wavelengths we could not interpret otherwise. Does it make sense to invent words for hues that we can't actually see and share with others? 2009/11/6, Cap'n Jimmy <flyboy@xxxxxxxxx>: > Blink...a blue and pink amalgam (stripes, checkerboard or plaid) > for the gender challenged > >
