Color Spaces and Conversions
What is CMYK?
Stands for Cyan, Magenta, Yellow, Key (Black). While screens (RGB) produce color with light, printers (CMYK) produce color with ink. Always check CMYK values if you are designing for print.
RGB vs HEX
Technically, they represent the same thing. HEX code is a shorter hexadecimal representation of RGB values. Browsers process both at the same speed.
Accessibility (Contrast Ratio)
Web Content Accessibility Guidelines (WCAG) require a specific contrast ratio between text and background.
Level AA: At least 4.5:1 ratio (For normal text).
Level AAA: At least 7:1 ratio (Higher readability).
This tool automatically calculates which is more readable when white or black text is placed on your selected color.
