Have to admit, none of our silvers are that dark on their winter hair! But I've seen pics of some that are almost that dark (look black) when shed/clipped for the show ring, so guess that would be possible
Our 2 homozygous silver mares are also both heterozygous black - and look golden when they are shed out after they fade in the sun and with their winter hair. They have both been mistaken for palomino, LOL.
January 2012 - Bell & Bit. Bit is closest to us in this pic (drives on the off or right side). They are 20 & 21 yrs old in this pic
May 20th, 2012 - Bell is 20 yrs old.
Koalah is our darkest mare - and has produced both our darkest foal and our lightest foal. Possible that the lightest is homozygous silver - haven't had her checked yet. Koalah is homozygous black, no agouti (bay gene), single silver, no sabino or frame, single tobiano.
Koalah & Ranger - 4 May 2010. Ranger is heterozygous for cream, silver & black. Only foal out of Koalah to not be a pinto, however at least 2 stallions she was bred to were homozygous for tobiano...
A pasture full of "faded" silvers - several are homozygous black, some are heterozygous black. 5 are only 1 silver gene - 3 not tested yet. Of the 3 not tested yet, 2 of those are homozygous black. Flower is a silver bay 1/2 shetland - tallest pinto near the back of the silver fillies. The lightest filly, Bunny, in the "middle" - is homozygous black - foal coat turned white not long after birth and stayed that way until she shed out her yearling year. She looks like a light silver right now with gold highlights.
