No more pics...but she said this when I asked her about the color,
"If you look in the palomino rule book (at least the last time I showed on that circuit), they are allowed up to 1/3 dark hairs in their mane and tail. I know when Chelsea was here for breeding when she was younger, she was a bright bright gold. As she got older, she has gotten darker. I know when she came here last year, Al and I were in Missouri on vacation. Shawna called and said she looked like a pumpkin LOL. Her filly that she had out of our sorrel stud, was a champagne color until she was about 2 and then started to darken up."
She could very well be a palomino, just not an ideal colored palomino. My godsister had a Palomino foxtrotter that was almost that exact same darker color, but was definitely a palomino. You would need to know her bloodlines though to be sure. The Foxtrotter was registered, so we had all the information on her.
