1954 Ferrari 375 Plus

Question:  When did you discover that the number on the roundels are accurately different colors on each side of the car?  

🤣

@marlowe-or-marty Is that how you tell if it's coming or going? Delineating 'port' and 'starboard'? There's got to be some reason.

I doubt there is any real reason for the different number colors. Smokey Yunick's 1962 Watson Roadster he tried the wing on at Indy had three different number color combinations on it. 

Front had gold numbers in a black roundel.

Right rear had black numbers in a gold roundel.

Left rear had white numbers in a gold roundel. 

Shelby American had white roundels with white numbers defined by red on the right and left doors/fenders on their 1963 Cobra. 

On the hood and trunk they had white roundels with black numbers. 

I have tried searches but nothing comes up with an explanation as to why this was done in different racing series. 

That is one great Ferrari Rich. It was not supposed to be good enough to win LeMans in 1954, but surprised all. Thanks for this one.

Just a note on the number colors, another 1954 Ferrari 375 Plus was number 19 and the numbers all matched side to side. 

There is a reason for the different colors.  I can't say I definitively know but I believe it had something to do with making the numbers visible to track stewards that tracked the laps completed at a race during nightime
