Chameleon color? Come on!

Look, I like FLOR as much as the next guy.  In fact, probably more than the next guy.  We use it in the bedroom because if Trev (or CoCo) has an accident, you can change out just that 1 tile.
.
Having said that, I find this picture less than helpful.
.
The colors of five different FLOR tiles are listed as "Chameleon, Hummingbird and Iguana".
.
Hum...
.
First, those are only 3 color names and there are 5 colors.
.
Second Hummingbirds come in any variety of colors - not a helpful name.
.
Third, I don't see a dirty sand color, so I have no idea which tile "Iguana" is.
.
Finally.  "Chameleon"?  Really?  Isn't that the animal that can change its color to suite the background.  It would be quite a trick make a FLOR tile that could do that.
