What is a Hex Color Code?

A hex code is a 6-digit value that represents a color in the RGB model. It starts with a # followed by pairs of digits:

• #RRGGBB
• Each pair defines the intensity of Red, Green, Blue (0–255).
• Example: #FF0000 = Red, #000000 = Black, #FFFFFF = White.

👉 Quick stat: W3C officially names 147 standard CSS colors, but hex codes allow for 16,777,216 unique combinations. That’s why designers rely on them for precision.

Hexadecimal Basics (The “Hex” in Hex Code)

Why hex? Computers speak binary, but binary numbers get long fast. Hexadecimal (base 16) is compact and converts neatly into binary.

• Decimal: 0–9
• Hexadecimal: 0–9, A–F (where A=10, F=15)
• Example: FF = 255 in decimal.

This means a hex code like #FF0000 equals RGB(255,0,0).

💡 Developer Insight: Most devs don’t memorize binary—but understanding hex helps when debugging colors across frameworks.
