RGB to HEX Converter

When You Need RGB to HEX Conversion

RGB values are common in design tools, color pickers, and programmatic color generation, but HEX codes are the most widely used format in CSS, design handoffs, and brand guidelines. Converting rgb(59, 130, 246) to #3b82f6 is something developers do daily.

Our converter takes R, G, B values (0-255 each) and produces the standard 6-digit HEX code. It handles edge cases like single-digit hex values (0-15 need a leading zero) and validates that input values are in the 0-255 range. The output is CSS-ready — just copy and paste.

This is particularly useful when extracting colors from design tools (Figma shows RGB by default), converting between color systems during development, and matching colors to framework utilities like Tailwind CSS or Bootstrap.

Tips

• RGB values range from 0-255 for each channel. Values outside this range are invalid.
• Each HEX digit pair corresponds to one RGB channel: RR=red, GG=green, BB=blue.
• Use HSL instead of RGB when you need to adjust brightness or saturation — it's more intuitive for those operations.
• CSS custom properties work with any color format: --brand: #3b82f6 or --brand: rgb(59, 130, 246).
