Wow lots of questions lol. I love questions :)
In terms of finding any that are as light as her, there are plenty. It is not the darkness of the coat that makes a horse brown instead of bay. Brown can be really light in itself, but it will still have the paler flanks and muzzle etc. While we can't see the soft part of your lady's muzzle, we can see her flank, where she shows a definite lighter shade.
As far as I am aware, there is no test yet for splash.
As for blue eyes, I do not believe there is any reason to associate them with tobiano. I also do not believe that it is associate with sabino. However, it is hard to say for definite if it is any of them, as we only have a test for tobiano, frame and sabino 1 (there is thought to be at least a sabino 2, if not more).
Lol I had to temper those questions so there wasn’t 5 more
Can you direct me to any one pic of the many horses as pale/light as she is please?- Cause honestly I havent found a SINGLE horse who is confirmed Seal via testing to look this light (I have seen lighter than almost 'normal' looking seals but not this light), however I have seen a fair few (who to be fair have had no testing for Seal as far as I know) that look much like her that are considered counter shaded/smutty/burnt 'bay' buckskins.
Yes I understand a little about Browns - I've had a few lol (some from foal to full grown with extra modifiers on top as well). I have never had an overly pale seal brown horse tho – can you direct me to this variation of Seal brown please? I'm interested to see for myself how pale they can get, as all mine have been much of a muchness colour wise & as far as I knew Seal was just the black being expressed over the horses body aside from the soft parts, so very interested to see how this 'black' pointing can be diluted with out other modifiers at work
Cynder looks Seal Brown + creme in Winter- in summer not so much at all- however it is hard to tell with so much white, but her flank & side of her belly on the larger spot look to be the same colour as each other rather than paler flank, darker belly area....I do know that counter shading/ smutty can & do get very dark over winter esp over the head & neck area, which is why I am resisting the temptation of calling her Seal Brown- I'll try get some new pics of her now she's in her summer coat for all to take a look at.
I'm not really interested in I 'think' this is seal brown & creme examples, Im after it's 'proven' Seal Brown & creme examples
If there's a strong chance she is Seal I'll spend the $100 & get her tested, I wont if I can't see another very pale/light coloured confirmed Seal Brown buckskin tho as it'd be like burning that $100 when I got the neg At results back & this close to christmas, burning $100 is not really an option lol
