For comparison here is a picture of our Phrag. Eric Young flavum, made with longifolium album crossed with besseae flavum that is currently in bloom:
I actually prefer it to have some red pigments in the flowers and think it looks nicer than if it was all yellow. It does look different compared to a regular longifolium crossed with a besseae flavum:
Like Jason mentioned, the reason you still get red pigments when you cross the longifolium album with the besseae flavum is that we are probably dealing wtih two seperate genes. aaFF x AAff (aa being album and ff being flavum: any plant that has Aa or AA will have red pigments and any plant that has Ff or FF will have red pigments), so when you cross the two together you end up with AaFf resulting in red pigments.
The only way to get an all yellow plant is by selfing or sibbing the AaFf plant. some (about 25%) will end up being aaff which will result in a total lack of pigments.
When you backcross this Eric Young flavum to either of its parents (so AaFf x aaFF or AaFf x AAff) you still won't end up with aaff plants and will still get for the most part colored offspring (there will be a very small percentage due to mutations of genes and other genetic factors that will end up aaff and be pure yellow).
