I recognize these photos because I posted something similar last October 6, 2012

The rooster in the top photo was described as "As colorful as you would like" so not necessarily ideal but advising that he may still be suitable but you would not want to use anything more colorful than this, so somewhere between him and the really pale rooster would be more ideal.
Emily de Gray is in the breeders page and I for one am not willing to doubt her breeder experience, advice or knowledge and I am not sure she or Jill espouse about really pale birds.
I feel that no matter what is said the genes will in the end denote what is possible. I am a big fan of test breeding any bird at this early point in the breed here in America. Even if a track I take proves unfruitful for creating a better Cream Legbar there is knowledge to be garnered from the journey and with my original gold bird that is soooo true but the same is said with her original mate with opposingly positive results.
I think in breeding these birds that the cream gene expresses itself inconsistently dependent upon the level of autosomal red but that is something I am still looking at in my own pens. I look to the secondaries and saddle for signs of gold and the shoulders for chestnut levels.. I have also found that the saddle does lighten itself over time. Hens have only one copy of cream is what I got from Niclandia early on in this discussion so I am assuming that the level of autosomal red has an affect on the tone of the that expression as I have some really cream hackled birds with more red at the throat and breast and my really pale cream birds with pale breast and clean throat areas. So you can have a slightly colorful rooster mated to a cream hen and get a nicely colored cream rooster with the right genetic pairings. The hackle and saddle color is not the same genetic color as the shoulder is where the discussion was heading I believe. My grasp of the correct scientific language is not great but it is interesting to see these topics pop up over and over again and the different levels of discussion that arise each time. I hatched a lot of chicks recently due to my situation and have gotten a good number of nice cream colored pullets and a fair amount of gold ones but not as many as i was expecting so I have a few thoughts bubbling up in my head I cannot put words to yet. I am rethinking my pens and rethinking my pens given the discussion topics here and what I see in my own birds. I am thinking of what Steen posted (on another thread) regarding brother to sister matings, adding outside stock for mating and then line breeding. I think I have enough pen space to try that next year I think. In regards to the dark down we had a discussion much earlier on about the tone of the down and if I remember correctly there was discussion on the dark being single barred but perhaps still cream due to the tone being more gray but I am not remembering if there was any resolution.
Sorry for the long post but I've been doing a lot of looking at my chicks and pens and have a lot of thoughts percolating in my head. I need a get-away vacation to give me a mental and visual break.
