Color

Main and secondary colors, balance ratios, and correct vs incorrect usage.

Our colors

Leonardo color is led by Brand Blue. Teal signals interaction, Ember adds rare emphasis, and cool neutrals keep reading surfaces calm. Use only approved values—do not invent tints outside the system.

Main colors

Main colors carry brand recognition. Brand Blue is the default for heroes, navigation ink, and primary identity moments. Deep Blue supports large brand fields. White and soft inverse keep content legible.

Secondary colors

Secondary colors support hierarchy and UI. Teal is the interactive accent. Ember is a highlight used sparingly. Neutrals (canvas, muted, secondary ink) structure layouts without competing with Brand Blue.

Color balance

Balance keeps Leonardo recognizable without feeling loud. Let neutrals carry most reading surfaces, Brand Blue lead brand moments, and accents stay scarce.

  • Neutrals

    60%

    Canvas, white, and muted surfaces for reading and structure.

  • Brand Blue

    30%

    Heroes, navigation, key identity blocks, and primary CTAs.

  • Accents

    10%

    Teal for interaction; Ember only for rare highlight moments.

  1. 01

    Lead with blue

    Open brand moments with Brand Blue fields or gradients that still feel blue-first.

  2. 02

    Rest on neutrals

    Shift long-form content onto white or canvas so type stays calm and readable.

  3. 03

    Accent with intent

    Use teal for interactive cues. Reserve Ember for a single emphasis point per view.

Correct and incorrect uses

Do

Use Brand Blue on white/canvas for identity. Put white or Ink Inverse type on Brand Blue. Use teal for links and focus. Keep Ember as a small highlight.

Don’t

Don’t place Ember text on teal, light gray on white, or rainbow gradients that dilute Brand Blue. Don’t convey meaning by color alone.

Correct · Blue on light

Brand Blue type or fields on white/canvas.

Correct · White on blue

Ink Inverse / white on Brand Blue heroes.

Incorrect · Ember on teal

Low clarity and off-system pairing.

Incorrect · Washed gray type

Fails contrast on light surfaces.
