Frequently asked questions
What's the difference between HEX and RGB?
They represent the same colors differently. HEX uses base-16 notation (#FF6B6B), while RGB uses decimal values (255, 107, 107). Both are additive color models for screens.
When should I use HSL?
HSL is ideal when you need to programmatically adjust colors. Want a lighter shade? Increase L. Want a muted version? Decrease S. It's the most intuitive format for developers.
Why do my colors look different in print?
Screens use RGB (additive light), printers use CMYK (subtractive ink). Some vibrant RGB colors can't be reproduced in CMYK. Always convert and proof before printing.
What is a color space?
A color space defines the range of colors that can be represented. sRGB is standard for web, Adobe RGB is wider for photography, and CMYK is for print.
