How Color Conversion Works
RGB to HEX: Each RGB value (0-255) is converted to hexadecimal (00-FF). For example, RGB(255, 0, 0) becomes #FF0000. The conversion formula: HEX = (R × 65536) + (G × 256) + B, then converted to base-16.
HEX to RGB: Each pair of hexadecimal digits is converted to decimal (0-255). For example, #FF0000 becomes RGB(255, 0, 0). The first two digits are Red, middle two are Green, last two are Blue.

Color Format Best Practices
- Use HEX for CSS and HTML - it's more compact and widely supported
- Use RGB when you need alpha transparency (RGBA format)
- Always include the # symbol with HEX codes in CSS
- Document both formats in design systems for flexibility
- Use uppercase for HEX codes for consistency (#FF0000 not #ff0000)
- Test colors on different displays for accurate representation
💡 Pro Tip
HEX shorthand: Colors like #FF0000 can be shortened to #F00 when each pair of digits is identical. Our tool automatically handles both 3-digit and 6-digit HEX codes for maximum compatibility.
Frequently Asked Questions
What's the difference between RGB and HEX?
RGB uses decimal numbers (0-255) for each color channel, while HEX uses hexadecimal (00-FF). They represent the same colors, just in different number systems. HEX is more compact and commonly used in web development.
Can I use RGB in CSS?
Yes! CSS supports both rgb(255, 0, 0) and #FF0000. RGB is useful when you need transparency with rgba(255, 0, 0, 0.5). HEX is more compact for opaque colors.
What does the # symbol mean in HEX codes?
The # symbol indicates that the following characters are a hexadecimal color code. It's required in CSS and HTML to distinguish color codes from other values.
Are 3-digit and 6-digit HEX codes the same?
3-digit HEX codes (#F00) are shorthand for 6-digit codes where each digit is doubled (#FF0000). They work identically but 3-digit codes only work when each pair of digits is the same.
