#FF7538
Crayola color
Overview
Orange, as Crayola defines it, is a warm red-orange at rgb(255, 117, 56), hex #FF7538. The full red channel with mid green and low blue places it at 18 degrees on the hue wheel — closer to red than the CSS orange keyword — at high saturation and brightness. It is one of the Crayola crayon range's core colors. Compared with the web palette's #FFA500, the Crayola version leans redder and warmer, a bright pigment orange balanced for vivid coloring. Its redward lean sets it apart from the yellower CSS orange, and because it sits opposite the blues on the color wheel, it reads with high energy against cool backgrounds.
Orange Crayola (#FF7538) is Crayola's signature orange crayon — deeper, more red-shifted, and richer than CSS orange. The Crayola orange has been a staple of children's art for over a century and carries enormous nostalgia in North American culture. Its warm, saturated character is associated with Halloween, autumn leaves, and classic cartoon aesthetics.

คุณสมบัติ
จิตวิทยาสี
True orange embodies enthusiasm, creativity, and adventure. It stimulates mental activity and social interaction, making it a favorite in creative industries. Orange is highly visible and conveys confidence without the aggression of red, bridging warmth and energy.
Design Usage
Medium orange excels in CTAs, pricing highlights, and gamification elements where excitement is desired. Tech companies and SaaS products use it to differentiate from the dominant blue of their competitors. It requires careful contrast checking since mid-range orange can fail WCAG on light backgrounds.
