Hello, I love this mod. But I still replaced the dull, dark horses with the one from Isabelle's Griffin Eternal mod. I would replace them all with ones that match the color scheme (from the Knight, Godric, Duncan, etc.), but I don't understand scripts. I see that individual mounts have been made for the Warlocks and Mages; I would like the same for the Knights. Here are some good screenshots in the archive.
But you don't need to understand scripts. Open the mod as an archive (using WinRAR, for example), find the horse image (in ".dds" format) there (just click around, you'll find it quickly; there are characters and something else). Then, find any program on the internet that allows you to open and edit .dds files; if necessary, this is a type of image format. And that's it. Open the image in the program and start painting the horse image 
. No scripts, just the talent of an artist
UPD: Basically, you can take the mod from this topic for people as a basis, then replace the horse model with your own (Isabelle's) in each character's folder, and then sit and paint each one manually :D. This way, you will have both the current mod from this topic with different characters and Isabelle's horses, and different horse colors; you don't need to code anything, just paint pixels. It will take a lot of time, but you won't have to think too much :D
