Re: HYB:  TB:  Pink

Problem is getting a pure pink that doesn't carry any purple or yellow. When
there is just one dose of anthocyanin inhibitor there is usuallly a faint
purplish flush to the bloom, especially on first opening. Also need to breed
out any expression of yellow. You can sometimes get very pure pinks from
using red bearded pure whites, at least on one side. These have at least 2
(often 4) doses of anthocyanin inhibitor and you know they don't have yellow
(there is no yellow inhibitor) but they usually carry pink  but just don't
have the 4 copies of the gene needed for expression.
Beard colour is not totally related for bloom colour so you also need to get
your beards to not be expressing yellows which will turn your pink beard
into tangerine (think this is how it works),

Basically your trying to get full expression of recessive pink genes and at
least 2 doses of the anthocyanin inhibitor ( or no anthocyanin genes at all)
and no orange or yellow genes.

Have fun.
