From your introductory thread it was determined that your budgie is a female.
On the photos, there is some blue on the edges of the cere and a lot of white colour in between and around the nostrils. These are the typical colours of a immature female or a female who is currently out of breeding condition.
Adult male budgies have rich and deep royal blue coloured ceres. In certain colour mutations, males can keep the immature pinkish/purplish colour on their ceres.
