Uses # followed by 6 hexadecimal digits (00-FF) representing Red, Green, Blue values. Example: #FF5733 means R=255, G=87, B=51.
🔴🟢🔵 RGB (Red, Green, Blue)
Represents colors using Red, Green, Blue values ranging from 0-255. Commonly used in CSS. Example: rgb(255, 87, 51).
🌈 HSL (Hue, Saturation, Lightness)
Defines colors using Hue (0-360°), Saturation (0-100%), Lightness (0-100%). Intuitive for adjusting color brightness and intensity.
💡 Tips for Web Designers
For web accessibility, maintain a contrast ratio of at least 4.5:1 between text and background. Using HSL makes it easy to create variations of the same color by simply adjusting saturation and lightness values.

Frequently Asked Questions
Q. What is a HEX color code?
HEX (hexadecimal) represents colors using base-16 numbers in #RRGGBB format. Each pair represents Red, Green, Blue from 00-FF (0-255). Example: #FF0000 is pure red.
Q. What's the difference between RGB and HSL?
RGB defines colors by mixing Red, Green, and Blue values. HSL uses Hue (color type), Saturation (intensity), and Lightness (brightness), making it more intuitive for color adjustments.
Q. Which color format should I use for web?
CSS supports HEX, RGB, and HSL. HEX is compact and commonly used, RGB is great with alpha transparency, and HSL is useful when you need to adjust colors programmatically.
Q. How do I copy color codes?
