OK, take a look at this pony here: twiddledittle.deviantart.com/j... You're looking at the pegasus one, specifically her mane. How would I go about keeping that shape, while basically braiding the two colors together? If you need more detail, just ask.
OK, think spirals of both colors (purple and blue), one spiral going clockwise, the other counterclockwise. They're sort of like if you take two slinkies and push them into one another. How would you make hair shaped like that? Love the pic BTW.
