BF Goodrich radial T/A white letters

I have not seen BFGs with brown letters.
In fact;
the 235s on the front of my Barracuda are about 20 years old, and NOT brown. and
the 295s on the back are pretty old too, and not brown either.
The car is always parked outside, but usually in the shade.
But, hey, I live in Canada up near the 50th parallel, lol. Our air is fresh, and clean, and right now, cold, lol.
