What about purple?<p>As a side effect of a meditation technique I use, I several times daily look for one each of objects in my environment that are red, orange, yellow, green, blue and violet.  Blue takes a long time to find and purple takes longer.  If sci-fi screens are blue bc of rarity, wouldn&#x27;t purple be a choice, too?<p>I think blue and purple are strange and rare.  But purple probably has too many connotations with little kids&#x27; arts and crafts or quirky old people.<p>And we don&#x27;t have to limit ourselves to what is natural, we can consider things in the man-made environment.  We tend to make many more things blue than we do purple.<p>Looking around my desk:<p>Blue things:  static mat, phone LED, supply label, USB cable, sticky notes, Outlook, mouse pad, pen, bananajack, map, medicine bottle cap.<p>Purple things:
