Hello Jerry,
I've never bred the BLRW in US. I have seen some photos of some vary pale blues.....but I think they are blue. Have you ever tried test mating your buff laced birds to see what happens?
When in UK I bred BLRW imported from Germany with usual result, for the lacing, of the 25:50:25 thing of Bl//bl+. I also made buff laced gold using dominant white. The laced red is probably more striking than laced gold.
I can only think of splash or dominant white that could give the white lacing to either red laced or gold laced. And you wouldn't see any BLRW if they had dominant white....because the lacing would show as white. Splash, which can also used to make the Jubilee Indian Game, can sometimes show few or no flecks.
