I posted on here a few months ago about asking for help with paulie's mutations, I was told he may be a mauve violet golden face (possibly double factor golden face or yellowface type II) cinnamon budgie, but in a just a few months his colours and markings have changed so much and I'm not very good with mutations so I would love some help, he looks so olive now.
His colour change is due to the yellow spreading, but that doesn't change what his mutations are. Are his markings brown? They look quite black in the second picture? His body colour is quite pale also, but that may also be due to the photo. Perhaps a photo of his wing markings may help.
The cinnamon can lighten the colours a bit. The second photo loos like the markings are just a darker cinnamon so I would go with him still being a mauve yf2 cinnamon. The first pic looks a little bit violet as well.....
