The If You Know, You Know color is a legendary DeLong secret. At first glance, this brown worm with a grey belly looks simple—even boring—but anglers who have fished it for decades know the truth: this is the most underrated and most effective worm color DeLong has ever made.

Its natural earth tones mimic real forage like nightcrawlers, leeches, and bottom-moving prey. Older anglers have used this color for generations because it consistently outfishes brighter, more modern patterns. Many say it’s their #1 confidence color, even if it doesn’t look flashy on the rack.

If you want the color that “old timers” insist on—and the one that quietly puts more fish in the boat than any other—this is it.
