Why it works and how to use it

Ultraviolet Glow is a vivid split color palette tagged dark, vibrant, cold. A split scheme: Grape plays against Turquoise across roughly 106° of hue. Saturation runs high, so use the brightest color sparingly and let the others carry the surface area. The overall temperature is cool.

The palette holds together thanks to its split hue relationship and a strong light-to-dark ladder (83% down to 8% lightness). A natural fit for websites, presentations and branding.

Background: Turquoise (#00F5D4) is the lightest color, so it belongs on large surfaces.
Text: Obsidian (#10002B) on #00F5D4 gives 14.2:1, passing WCAG AAA.
Primary: Mauve (#E0AAFF) is the most saturated mid-tone; use it for buttons and links with a border or a darker shade for contrast.
Accent: Grape (#7B2CBF) for highlights, badges and hover states.

3 of 6 color pairs pass WCAG AA (4.5:1); the strongest is Obsidian on Turquoise at 14.2:1.
