Neon Blue
Also known as: Vaporwave Blue, Berta Blue, Splashing Wave, Ionized-Air Glow
Neon Blue is what happens when cyan turns medium and vivid. The effect is crisp and refreshing, made for modern branding and tech interfaces. Match it with red accents when the design calls for energy over calm. Against dark backgrounds it stays legible (12.37:1), but avoid it as text on white.

Where Neon Blue works
- Web & UI: Reads as an interactive accent: fills, hovers, focus rings. Keep body text in a darker neutral.
- Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
- Fashion: One garment in this color carries an outfit; two starts to compete.
- Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
- Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
- Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
