SBIX Roman lettering color-red or black?

nyc3001 .

The PDS that comes with the Sunshine vinegar tank car kit mentions two lettering styles for Standard Brands: a red Roman lettering and a black sans-serif lettering. However, the kit that I have comes with black Roman decals and reweigh dates in the late '40s and early '50s. Was this lettering accurate for the vinegar car around this time?
