I noticed that my sable buck changed colour alot from 7 weeks old to now (almost 4 months old) and it's stillchanging but slower now. He started off being a dark blackish brown allover, then slowly his body got lighter and his nose ears tail and feetstayed dark. Now his body is quite light ash brown and he is getting adark mask shape over his face around his nose, mouth and eyes.
I think a lot of pointed colour rabbits change often during the year.My old seal pount Ben, his points would vary from grey to chocolateybrown depending on the time of year and how hot or cold it was. Hiswhite body would also darken in winter.
