* Black horses can definitely produce chestnut horses - if a black horse is carrying both the red gene and the black gene, it will display physically as black but CAN produce red foals (if s/he has the red gene). It's a chestnut horse that cannot produce a black horse - if bred to a chestnut or any variation of chestnut, the foal will always have a chestnut base.
* The dorsel stripe does not distinguish a dun from a buckskin - buckskins can easily have dorsel stripes if counter shading is present. Often the zebra striping is a giveaway, but counter shading CAN also cause that, so there is no tried and true way to distinguish a buckskin from a dun unless you know the parents or have blood testing done.
* I would work on your Pinto colors page. The picture of the tobiano is actually a tovero (the face is a giveaway that one of the overo genes is also present), and tovero is a bad term - overo only means that the horse is sabino, splashed white or frame overo, and the picture you have labelled as "overo" is actually a frame overo horse, so I would remove the overo and clarify to your readers the differences between tobiano and the three overos.
* The manchado picture with the Pinto photos is misleading - manchado is not a Pinto gene, it is a rare color condition only found in Argentina horses and is widely believed to be a situation of environmental effects and not an actual color at all as it has appeared on horses that do NOT carry pinto or appaloosa.
Not a bad website at all, but I would definitely try and involve more info. You did pretty good for the base colors, but once it got more complicated, you opted to just post photos and provide little explanation which is usually what people are looking for - WHY is a horse this color, what breeds are this color, etc.
Best of luck!
