Difference between Colors from Supreme and Ultra Editions? (S3)

The description for Ultra says it includes: “bonus retro color 7 for all Season 3 characters”

Supreme says: “bonus colors for Season 3 characters”

I’ve bought every Ultra edition so far except season 3. Am I going to have to pay ten extra dollars just to get more colors from the Supreme edition, or are the colors the same as those in Ultra Season 3?

They are the same.
