Suggested color roles

primary

#00008B (Dark Royal Blue) - Establishes the core identity, suitable for main interactive elements, primary buttons, and significant data displays. It provides a strong, serious foundation.

secondary

#1E90FF (Dodger Blue) - A slightly lighter, more energetic blue for secondary actions, active states, or sub-headings. It offers contrast and visual interest against the primary.

accent

#00FFFF (Cyan) - The glowing highlight color for critical alerts, interactive indicators, focus states, and atmospheric light effects. Use sparingly for maximum impact.

background

#000033 (Very Dark Navy) - Provides a deep, immersive canvas that enhances the luminosity of lighter blues and cyan. Ideal for dark mode UIs and spacious digital environments.

text

Recommend white or near-white (e.g., #FFFFFF, #F0F8FF) for primary readability on dark backgrounds. For secondary text or less critical information, a lighter blue like #4169E1 can work.

Accessibility notes

Ensure #00FFFF (Cyan) has sufficient contrast when used for text against #000033 or #00008B backgrounds; often requires larger font sizes for readability.
Use white or very light grey text (e.g., #FFFFFF) for primary content on #000033 and #00008B to meet WCAG AA contrast standards.
The #4169E1 blue can serve as a readable text color for secondary information on the darkest background, but always verify contrast ratios.
Avoid using #00FFFF for large blocks of text due to potential eye strain; reserve it for small, impactful elements or icons.

Recommended combinations

Deep Interface

Ideal for foundational UI elements, background panels, and primary interactive components where depth and clarity are key.
