The colour of the silver Bengal is the result of the inhibitor gene that stops the production of Pheomelanin. It is not actually a colour, but a lack of. In order to produce a silver Bengal, at least one parent must be silver.
The silver Bengal has two or three shades of colour with a white background and dark grey to jet black markings. The coat has zero or as little tarnish (brown) as possible. The tail tip is always black.
The silver Bengal has brick red nose leather and green coloured eyes.
