Why it works and how to use it

Cassette Tape is a complementary color palette tagged retro, red, white. Near-complementary hues (about 152° apart) make this a high-contrast, attention-grabbing combination. Saturation is moderate, which keeps it flexible for both interfaces and print. Warm and cool hues are mixed, which adds depth.

It works because the lightness range is wide (17% to 96%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.

Background: Smoke (#F1FAEE) is the lightest color, so it belongs on large surfaces.
Text: Gunmetal (#2B2B2B) on #F1FAEE gives 13.25:1, passing WCAG AAA.
Primary: Vermilion (#E63946) is the most saturated mid-tone; use it for buttons and links (3.9:1 against the background, fine for UI elements).
Accent: Steel Blue (#457B9D) for highlights, badges and hover states.
