Pink and off white, not a bright white.
Best seersucker looking cloth I used was 100% wool from Zegna. Three color ways, light blue, bordeaux /red, and a green. All on an off white/cream ground. 6/7 ounce with amazing body from the weaving. The green was a perfect soft shade of green and my favorite of the three. Cloth sold out before I could reorder but I would have bought a bunch of it after learning how well it made top and looked.
IIRC, Loro Piana has a silk seersucker in their books at present. It's a little "precious" looking, not sure what I think about using it.
