T- Albino is also a recessive trait, and this is the classical albino we all know which has no tyrosine and has no dark pigment (melanin). This results in a House Snake, showing a yellow, orange and white colouring and their pupil is red. House Snake being nocturnal have a vertical pupil, which only appears as a tiny vertical slit during the day, this makes it hard to see the colour of the pupil. In a dark room or at night you will see the pupil is dilated and will clearly be red. Depending on locality of the snakes the orange and yellow can vary greatly with the different shades of brown in the wild types. On the more red varieties the orange can be very bright almost going towards pink.
