A number of modern whites, creams and violets include pinks in their 
ancestry. One parent of LAVENDER PARK, for example, is Bill Maryott's 
DELIRIOUS which has a tangerine beard.  Some others that look likely 
to breed tangerine beards include ELIZABETH POLDARK and DEVONSHIRE 
CREAM.  There are many such.

In crossing pinks with non-pinks the first generation will be creams 
or yellows instead of pinks.  The pink pigment is simply yellow 
altered in its chemistry by the "t" factor.  To recover pinks and 
pink or tangerine beards you need to cross back to a "t" parent.  
Then, only a fraction of the seedlings will have the red or pink 
beard if the white (or other non-pink) had NO tangerine factor.  
Fortunately, many irises do.  

However, the basic cross you describe has been done many times--
you'll save much time if you build on the rich foundation of 
materials already available on the market.

You are also fortunate that most modern pinks (or other colors with 
tangerine beards) do already include whites or blues in their 
ancestry.  Melba Hamblen used Helen McGregor and Great Lakes in 
crosses with t-varieties.  Nearly everything (if not all) of hers 
that survive include those crosses in their ancestry many times 
over.  The modern pinks that are not primarily Fay-Moldovan-Rudolph 
in ancestry often trace back to Hamblen pinks.  

Further backcrosses to whites or blues could add better forms, more 
ruffling, better growth and branching if the right parents are 
selected.  Consider FOGBOUND a ready made source---Babbling Brook, 
Honky Tonk Blues and others are in its pedigree and it has a delicate 
pastel tangerine beard to boot.  It is reported to be a very good 
parent.
