Lehigh Valley Steam Lettering color white or Silver

I am looking to decal several recently inherited steam locomotives in lehigh valley livery, I have silver and white decal sets and not sure which are correct. I have scoured the interenet for color photos of a valley steam and havent had much luck

Would anyone have any idea on proper lettering color.

The locomotive from the Black Diamond captured by Overland Models has white lettering, if that helps.

Walthers had O Scale steam locomotive decal - silver. Out of stock, discontinued
