You are absolutely correct on this Linda. A light wash of the anthocyanin delphinidin gives a bluish wash to the pink. A lot of the intense or hot pinks have a light wash of anthocxyanin,
A mix containing a bit more anthocyanin gives you a buff-tan colour such as on my Buckskin Babe.
But brown is a mix of yellow and a wash of anthocyanin.
Before lycopene started showing up, giving seashell pink as it was called then, there were some light lavender-pink iris called pink. These were actually as mix of pale yellow and a medium-light wash of delphinidin anthocyadin. There were a number of pallida species or near species cultivars that were of this "pink" colour. With the introduction of lycopene the definition of pink changed.

I think that the rosy pinks are a combination of the bluish pink and
tangerine pink. But not sure about that.
The combination of the two sorta looks like this, I think. Not positive
I got this photo matched up with the right pedigree, but I think this
one is from (PINK FORMAL x bee) X GOLDEN APPLE.
