So this is my night fury oc named magpie and she's a pied color mutation which is a thing that can happen to real animals also sorry it's sideways kinda i just thought it looked better that way when I began drawing it!

Here's real examples also some animals it's normal for them to be pied but others it's a relatively common color mutation (think of budgies) and for some it's an extremely rare color mutation but here we go (IMAGES NOT MINE)

There's the definition now for photos
