Red or Blue streak tires????

I have a Dark blue barracuda with body painted wheels with red streak tires. With the car color I was thinking of going to blue streak tires. The car is very much original and going to eventually take it to bigger judged shows.

Will I get dinged for the blue tires?? I know they had them in 66, but read where they were discontinued on cars in 67. I don't know for sure and hoping someone here does.
