What is the primary color of the Facebook logo?

The primary color of the Facebook logo is blue.

Facebook became strongly associated with a blue-and-white visual identity from its earliest years. The familiar design used a white lowercase “f” or wordmark against a blue background, making blue the dominant brand color. Modern versions of the logo have changed in shape and styling, but the central color association has remained.

The choice is often linked to Mark Zuckerberg’s red-green color vision deficiency, which makes blue easier for him to distinguish. That explanation is a well-known part of Facebook’s origin story, although branding decisions also involved readability, contrast, and consistency across websites and mobile interfaces. The blue is therefore not merely a decorative choice; it became a recognizable shorthand for the company and its social network.

A common mix-up is to answer white because the letter or wordmark often appears in white. White is a contrasting secondary color in the classic logo, while blue is the primary background and brand color. Facebook’s corporate parent is now Meta, but the Facebook service still retains its own blue identity.
