Claudia Winkleman is "orange" because she frequently uses fake tan, which has become a distinctive part of her public image and style. She embraces a very bronzed, orange-toned tan and has humorously acknowledged her love for the look, once saying she loves being orange. During filming of "The Traitors," she even used unconventional methods like gravy granules as a substitute for fake tan. Claudia has been committed to this signature tan supplemented with professional fake tanning sessions and a beauty regime aimed at maintaining her bronze glow. Despite past unhealthy sunbed use, she now prefers fake tan to achieve her trademark orange complexion. This orange tan is part of her unique look, along with her trademark thick fringe and dark hair, which many fans recognize as her iconic style.

In short, Claudia Winkleman's orange appearance is intentional, stemming from her use of fake tanning products and a distinctive, deliberate beauty choice that has become part of her brand.
