The 2025-26 FC Koln Away Shirt features a predominantly dark red base with a modern gradient effect that fades to a lighter tone at the bottom. Tonal vertical stripes are woven into a matte and shiny jacquard fabric, offering a refined, retro-inspired aesthetic. The design is complemented by a white crew-neck collar with red and black trim, matching the white hummel chevrons on the side panels and white sponsor logos for a sharp, high-contrast finish.
