Frequently Asked Questions

What is the difference between RGB and HSL?
RGB describes colors by red/green/blue channel intensities. HSL describes them by hue (color wheel angle), saturation (intensity), and lightness — more intuitive for design.
What is WCAG contrast ratio?
WCAG (Web Content Accessibility Guidelines) requires at least 4.5:1 contrast ratio for normal text (AA) and 7:1 for AAA. This matters for readability for visually impaired users.
What is CMYK?
CMYK (Cyan, Magenta, Yellow, Key/Black) is used in print design. It's a subtractive color model — mixing inks absorbs light rather than emitting it.
Can CSS use HSL colors directly?
Yes! CSS natively supports hsl(200, 100%, 50%) and the newer oklch() and lch() formats for more perceptually uniform colors.
