In the F1 , Sapphire Hills X Pencil Sketch, ther wer 2 of 3 seedlings
that were tangerine. Small numbers indeed to make any guesses but
since neither parent showed pink it would have to be Tttt in each
parent to give this high a number, unless as Neil says the t is in SH
as an epistatic gene as ttt but can't express as the other needed
factors are present.

In the 19 seedlings we seem to have the following tttt plants #4, #8, #11.

11 clearly shows the tangerine pink. #8 has pink infusions but not as
pink as 11. Put # 4 and a closeup of FoF on the scren together. The
closeup Margie posted address for works well. FoF has tangerine beard
but the standards are an apricot-yellow. Still seems to be a tttt but
some sort of co-factors change its expression. When #4 an FoF are on
the screen together the resemblence of colours is remarkable( as well
as flower shape) FoF is a luminata but #4 is the same colours but
without plicata or its subgroup luminata showing.

This gives us 3 out of 19 as tttt. This is a percentage of 15.79, very
close to 1/6 which is 16.75%.  This would be TTtt x tttt, so best fit
is that the parent seedling would be TTtt.

How about next group of factors is the factors controllin absence of
carotene and anthocyanin in seedling #9
