Palette strategy

A practical design system, not just five HEX codes

Brand hierarchy

Primary, secondary, accent, and support colors establish a repeatable visual identity.

Interface surfaces

Background, surface, text, and border roles help translate the palette into a usable UI.

Conversion actions

Button and CTA recommendations show where stronger colors can guide attention and interaction.

Contrast guidance

WCAG contrast checks identify safer text and background combinations for real projects.

Frequently asked questions

About the STEM Lab palette

What colors are in the STEM Lab palette?

The five HEX colors are #0B1933, #203F6C, #E54356, #F9DA6B, #F1F4F8. In descriptive terms they read as Deep Blue, Dark Blue, Vivid Red, Vivid Yellow, Pale Blue, giving the palette a spread from deep blue to pale blue.

Which color is the strongest anchor in STEM Lab?

#0B1933 is the darkest color in the set and is the strongest candidate for navigation, display headings, framing, or other high-priority hierarchy. The final foreground should be selected from the measured contrast pairs.

Which color should I use for a CTA?

#F9DA6B is the most saturated color in this palette, so it is a useful CTA candidate for actions such as “Continue lesson”. Use it selectively and verify the button text/background contrast before production.

What is the highest-contrast pair in this palette?

Among the five supplied colors, #0B1933 and #F1F4F8 produce the strongest measured contrast at approximately 15.8:1. The accessibility section on the page shows which combinations meet AA or AAA thresholds for specific text sizes.

Where does STEM Lab work best in education design?

It is particularly useful for a course page, especially when paired with students and educators. The palette is most effective when the five colors are assigned stable roles instead of being used at equal weight.

Can I export these colors for development and design tools?

Yes. The page exposes the five HEX values plus CSS variables, gradients, Tailwind configuration, SCSS, JSON, editable shade ranges, and links into the GEC Designs palette, gradient, and AI tools.
