Yellow spark from all plugs on bank one

Hey I’m having an issue where all the spark plugs on bank one are sparking yellow. All new coils and plugs. Any ideas what would cause this ?

Running Octane booster will coat your spark plugs in a orangish yellow coating every time. At least in my experience.
