blue0x3

Blue0x3 is a color token designation used in some digital design systems and asset pipelines to refer to a specific shade of blue. It is not a standard color name in CSS or HTML, but a convention found in token libraries and design kits to provide deterministic color values across platforms.

Naming and mapping: The suffix 0x3 signals its position within a family of related blue hues. In many token schemas, blue0x0 through blue0x5 or higher denote incremental lightness or saturation steps. The exact hex or RGB value attached to blue0x3 varies by project, but it generally represents a mid-tone blue suitable for primary UI components.

Usage: blue0x3 is commonly used for primary actions, links, or highlights in a design system. It is paired with darker or lighter variants for hover and disabled states, and with neutral colors for text and borders to maintain legibility.

Implementation: In practice, blue0x3 is implemented as a variable or token, for example in a CSS or YAML token file, where color-blue-0x3 resolves to a concrete color value defined in a palette. Projects map the token to hex or RGB values according to brand guidelines.

Accessibility: Ensuring sufficient contrast with body text and interactive states is recommended, and products often document contrast ratios for blue0x3 in relation to other tokens.
