oh! I was just wondering, so the realistic is for real dog breeds slash balto character's colors real, and unrealistic is for nonrealistic dog breed colors, right?

Real life is realistic, so yes, a dog breed/coat colour from real life would be called realistic.

Now Jenna is a Red Husky. We have red huskys in real life, so she would be put as realistic.
Although she's bright red, it's cannon in the movies for this red to be okay. So the Balto universe, this red is realistic
