Depending upon station in the early days the white Tamars were slip launched and the red/white anti fouled boats, kept afloat were changed to the white...….which wasn't white as such but a cream colour similar to the old colour of OLD ENGLISH WHITE.....which is sold for classic cars...……..but now, I believe all Tamars have taken up the "cream" below boot topping, which is that light cream, Old English White.
