thanks, I have black and I have more of this color. i probably will go with this color back to itself and avoid the "black box". i think it's a very pretty color even if it not khaki/dun. I do have sigrids first book, but not much is written about paints in it- should i be looking under another color (champagne)?
This colouring is very common in paints, and can occur (usually in a much lesser extent) in dominant white birds as well. I call it champagne. Genetically it is not khaki (I^D/I^D). I have produced a very few dun paints (dun spots on a white background), and if I can ever get them to maturity without stupid mishaps (horse stepped on the first, heat got the second and pool got the third), I will be following some breeding advice that should shed some light on paint.
If you are wanting to produce non-spotted birds of this colour, breed to black or together, selecting for the birds with the least spoting, rather than for birds with the most spotting, as paint breeders are doing.
There is some thought that this colouring requires that a bird be gold rather than silver; that silver paints are a cleaner white. If you can get a copy of Genetics of Chicken Colours or Silkies and Silkie Bantams by Sigrid van Dort, there is a fairly extensive writeup on paints, including this off colouring
