“Delta Blue” is the primary color expression for Delta audiences. A secondary tier of Delta Red may be used as an alternative background colors to Delta Blue. White should predominantly be used for typography on primary and secondary colored backgrounds.

Delta Air Lines' official brand identity in 2026 is built around a patriotic and professional palette of Navy Blue and Red, accented by a crisp White. Specifically, the logo uses "Ateneo Blue" (a deep navy) and "Special Red" (a vibrant, bold red) for its iconic "Wedge" or "Widget" symbol. This color scheme is reflected throughout their operations, from the dark blue tails of the aircraft to the "Passport Plum" and "Cochineal Red" tones found in their 2026 designer uniforms. The blue represents trust and stability, while the red signifies energy and the "forward-leaning" motion of the triangle logo. Inside the cabin, Delta utilizes "Delta Blue" mood lighting to help relax passengers during flight. When you see a Delta aircraft on the tarmac, you will notice the body is a clean, bright white (off-white) to help reflect heat, which makes the bold red and blue branding on the tail and engines stand out as the airline's primary visual identifiers.
