Understanding Color Formats

HEX Colors

Hexadecimal colors use a 6-digit code (like #FF0000 for red) representing RGB values in base-16. Each pair represents Red, Green, and Blue intensity.

RGB Colors

RGB uses decimal numbers (0-255) for each color channel. RGB(255, 0, 0) represents pure red with maximum red value and zero green/blue.

When to Use Each

HEX is popular in web design and CSS, while RGB is common in image editing and programming languages.

Frequently Asked Questions

How do I convert RGB to HEX?

Enter the RGB values (0-255) in the Red, Green, and Blue fields. The HEX code will be calculated automatically and displayed with a color preview.

What is the difference between HEX and RGB?

HEX uses hexadecimal notation (base-16) with values 0-F, while RGB uses decimal numbers 0-255. Both represent the same colors but in different number systems. HEX is more compact, while RGB is more intuitive.

Can I use these colors in CSS?

Yes! Our tool provides ready-to-use CSS code snippets. Both HEX (#FF0000) and RGB (rgb(255, 0, 0)) formats work in CSS. HEX is more commonly used for web design.

What programming languages support these color formats?

Most modern programming languages support both formats. Our tool provides code snippets for CSS, Swift (iOS), Objective-C (iOS/macOS), and Android development.

Are there any limitations to the color values?

RGB values must be between 0 and 255 (inclusive). HEX values use 0-9 and A-F characters. Invalid inputs are automatically corrected or ignored to prevent errors.
