Roux colors reflect how long the flour has cooked with fat and how that changes thickening power and flavor. White roux is cooked just long enough to lose the raw flour taste, typically about 2–3 minutes, leaving a pale color. Because the starch hasn’t browned, the granules swell most effectively when liquid is added, giving it the strongest thickening power. The flavor stays bland, which is ideal for sauces where you don’t want a roasted or nutty note.

Longer cooking turns the roux brown or dark, which develops deeper, toasted flavors but reduces thickening efficiency. That’s why the description of cooking for hours to a dark brown color doesn’t describe white roux.

A raw flour-and-water mixture isn’t a roux, since roux relies on fat to coat the flour and help it hydrate properly while cooking.

Roux is prepared on the stove and added hot to sauces to thicken, not used only at room temperature.
