Yellow tomato sauce?
 

Do yellow/orange tomatoes yield a yellow tomato sauce?

yellowish orange or both....I've traditionally made "mixes" of yellows and oranges for sauces, as well as pinks and reds, purples and blacks, yellows and greens, greens and pinks, yellows and reds....whatever turns your crank. I find the purples and blacks yield a very rich robust sauce....yummmmm. Love it for heavier pasta needs...something that requires a robust base.
