Frequently Asked Questions
What is HEX colour format?
HEX colours use hexadecimal (base-16) notation: #RRGGBB. Each pair represents a red, green, or blue value from 00 (0) to FF (255). #000000 = black, #ffffff = white, #ff0000 = red. HEX is the most common format for web design.
What is the difference between RGB and HSL?
RGB defines colour by red, green, and blue light values (0–255 each). HSL defines colour by Hue (0–360° on the colour wheel), Saturation (0–100%), and Lightness (0–100%). HSL is more intuitive for design — to make a colour lighter, just increase Lightness.
What is CMYK?
CMYK (Cyan, Magenta, Yellow, Key/Black) is used in print design. Unlike RGB (additive light mixing), CMYK is subtractive — inks absorb light. Digital screens use RGB; when designing for print, colours need to be converted to CMYK to ensure accurate reproduction.
