redyellow

Redyellow is a term used to describe hues on the warm side of the color spectrum that lie between red and yellow. It is not a standardized color name in major color systems, but designers commonly use it as a shorthand for orange-tinted tones along the red–yellow arc of the hue circle. In digital color models, redyellow corresponds to a range of values between red and yellow, with high saturation and brightness; exact representations vary by device and color space.

The term finds frequent use in branding and graphic design to convey energy, appetite, and attention. Logos, packaging, and user interface elements may employ redyellow palettes to create warm, vibrant visuals. In signage and safety contexts, red and yellow are used together to attract notice and signal caution, and redyellow hybrids can reinforce that effect.

Cultural associations with red and yellow differ by region but often emphasize warmth, celebration, or danger, influencing how redyellow palettes are applied. In art and photography, redyellow gradients or duotones are used to evoke heat, sunset, or dynamism.

Redyellow is more a descriptive label than a formal category, and it may refer to a palette, a gradient, a design theme, or a brand name in different contexts. See also orange, color wheel, color harmony, branding palettes.
