What is this color/pattern?

[Krys109uk]

So even though your bird may not meet the "standard" does not mean it's not an EE or BO or etc. etc.

There's never a 'perfect' bird, but if a bird doesn't broadly fit the type described in the standard then it cannot be that breed (EE isn't a breed). Delawares & buckeyes would have been breeding true to type before being named.​

The top bird seems to be about in the middle between yellow partridge and buff columbian in colour & pattern. The bottom one looks more wheaten than buff. Notice that the breast is lighter and the feathers are not quite unicolour.
