The adult female in the photograph is a visual T+ / Blonde Albino. This is a completely different appearance to the more commonly known T- Albino (such as Kahl & Sharp strain), that I assume you are thinking of?
This line of T Positive (Tyrosinase Positive) Albinos / Blonde Albinos have a genetic mutation that prevents the ability to complete the synthesis of melanin but can produce other melanin related pigments such as various shades of brown grey & red. This differs from the more well known T- Albinos such as Kahl & Sharp Strain in that areas that would normally be black or brown are typically white or yellow.
Yearling Blonde Albino
Visual Blonde Albino compared to a het.
Newborn T Positive Albinos (as seen in the pictures below) have little or no black pigment at all & tend to show grey pigmentation where black would normally be present, such as in the tail marking borders. As they mature, this grey colour will develop into a dark brown/black.
The resulting appearance in the adults is that of an attractive Pale caramel background colour and reduction of black pigment.
