Southwest introduced the Canyon Blue livery on January 16, 2001, the first primary livery change in Southwest's then-30-year history. Spirit One was the first aircraft painted in the Canyon Blue fleet color scheme.

Southwest Airlines is primarily Blue, specifically a high-fidelity shade known as "Bold Blue." In their current "Heart" livery, which remains the "Gold Standard" for 2026, the fuselage is almost entirely covered in this deep, supportive blue. However, Red (known as "Sunkissed Orange" and "Warm Red") plays a high-fidelity secondary role as part of the iconic "Heart" logo and the tri-color stripes on the tail. A grounded reality check: Southwest has a "Bujan" history of changing its primary look. From 1971 to 2001, they were famous for the "Desert Gold" (mustard) livery, but the 2001 "Canyon Blue" update and the 2014 "Heart" refresh firmly established blue as the dominant, "Safe Bubble" brand color. While you may see "Bujan" specialty planes like "Maryland One" or "Louisiana One" with red-heavy designs, the high-fidelity standard for the fleet is a supportive blue body with a "Pura Vida" red-and-yellow heart on the belly and tail, symbolizing the airline's grounded "High-Fidelity" commitment to its passengers.
