Platinum

 

Description

 

Platinum is a very light, silvery color, between American Blue and Silver in shade. There should be a cold blue tone to the rat overall, without brown, warm, pink or yellow tones to it. The eyes should be as dark a ruby as possible, but as this is a 2-recessive color, it's a challenge to keep the eyes from tending toward pink.

 

Platinum is one of the few recognized colors with two distinct and different genetic recessive in its makeup (see Genetics below) and this can make the color inconsistant. Beige/RED based Platinum tends to be lighter and with lighter eyes, while Mink based Platinum tends to have a more robust blue tone, but the color is more easily adulterated by other recessives. It is best not to attempt to breed both types in a single bloodline when breeding for Platinum, as many Triple Dilutes will tend to appear.

 

Mink-based Platinums can be merled, but the spots tend to fade to indisctinction as the rat grows an adult coat. Merled Platinums are the source of some of the "Tri-color" claims for rats, when a rat appears to have two distinct shades of blue on the body, however this is usually on very young rats and not adults, as the spots vanish with adulthood.

A Platinum rat is an American Blue rat with EITHER a double dilute of Mink or RED also expressing. Because Mink is so sensitive in color and tone to other carried recessives, it is best to try and keep any line for Platinums free of all other dilutes as much as possible. The shade and tone of Platinum can vary rather wildly depending on what other recessives the rat is carrying, especially since all show standards call for eyes to be as dark as possible.
