ok i'm sorry but that really didn't make any sense...
dominant white when heterozygous DOES allow leakage, that's what I was saying before.
but I have no ide what you mean by double blue breeding. a 'double blue' IMO would be a homozygous blue which IS splash... but I have no idea what you mean by canceling each other out.
'when breeding untrue colors'. um... no clue, again. sorry.
regarding paint silkies, I found this...

so back to the initial question of a half cochin and half gold sexlink producing a paint, my response is still the same. no I doubt it's a paint. what they look like are heterozygous dominant whites with color leakage. that occurs with nearly every dominant white crossed with another color. leghorns, sexlinks, whatever. I had a sultan roo breed a dark brahma hen and got a few of these.
the paint mutation (so far) seems to be limited to the silkies at this time.
