Frequently Asked Questions (FAQs)

What is WCAG Contrast Ratio?

Web Content Accessibility Guidelines (WCAG) dictate that text must have a minimum contrast ratio against its background (4.5:1 for normal text for Level AA, 7:1 for Level AAA) so visually impaired users can read your website easily.

What is the difference between HEX, RGB, and HSL?

  • HEX: Base-16 hexadecimal notation (#2F5FD6) commonly used in web design and CSS.
  • RGB: Red, Green, Blue intensity values (rgb(47, 95, 214)).
  • HSL: Hue, Saturation, Lightness values (hsl(223, 67%, 51%)), which make it much easier to calculate tints, shades, and harmonious color palettes programmatically.
