FAQ
What's the difference between HEX, RGB, HSL, and HSV?
HEX uses hexadecimal, RGB uses red/green/blue values, HSL uses hue/saturation/lightness, and HSV uses hue/saturation/value. HSV is commonly used in design software.
What is contrast ratio?
The ratio of luminance between text and background colors. WCAG recommends AA (4.5:1+) and AAA (7:1+) for readable designs.
Where is alpha (transparency) used?
For overlays, hover effects, shadows, and semi-transparent elements. Use RGBA or HSLA format in CSS.
