Brand GuidelinesVersion 1.0
ColorColor is a crucial tool in the Resend visual system. The palette is designed around sharp contrast between black and light, reinforcing precision and focus. Accent colors are used sparingly to communicate state, intent, and meaning within the product.

Our palette uses the Radix color scale to ensure consistency, predictable behavior, and accessible contrast.
Color paletteThe Resend core palette consists of Resend Black and Resend White. Together, they form the foundation of our color identity and are the primary drivers of brand recognition.

Black and white are used across both product themes, supporting light and dark mode experiences. Black is also the dominant color for all marketing touchpoints, where high contrast and consistency are key.

GrayThe gray scale is used for structure, hierarchy, and subtle separation.

Grays support secondary text, borders, dividers, disabled states, and background layers. They should never compete with primary content or accent colors.
