Z
this takes some real loosely made up colors------
Zero---------black is the absence of all light Or white-----------if you see it as the absence of all color.
Zoo-----------greenish brown
zenith------I'm thinking sky blue-------a far up as I can see
Zeus----------tan colored
Zennia-------------red for first choice, purple and yellows for 2nd & 3rd
Zombie----------gray?
Zing--------a bright color of chartreuse, purple, hot pink, electric blue----or Lemon Yellow for a zingy taste.
zepher---------that's a wind-------so some blue gray???
What would be the most fun with that challenge is reading what fun names folks came up with for every day colors.
