I see what you mean. The flames are certainly nice and blushed, but not as orange as what I am used to seeing. Mind you, your line is much darker tan anything I've seen as well. I think the amount of checkering on the sides more than makes up for it.
The dinker I have is orange. Side by side with any normal ball, he looks quite orange in overall looks.
I am really looking forward to see what his offspring looks like.
