How It Works

Enter your R, G, B values

Each channel is a number from 0–255. Red=255, Green=0, Blue=0 gives you #FF0000 (pure red).

HEX updates instantly

The HEX code refreshes as you type. Values outside 0–255 are automatically clamped to the valid range.

FAQ

Common Questions

How do I convert RGB to HEX manually?

Convert each channel from decimal to hexadecimal. For example, RGB(255, 128, 0) → FF (255), 80 (128), 00 (0) → #FF8000. This tool does it instantly so you don't have to do the maths.

Why does my RGB produce an unexpected HEX?

Make sure each value is within 0–255. Negative numbers or values over 255 will be clamped. Also, RGB(0, 0, 0) is black (#000000) and RGB(255, 255, 255) is white (#FFFFFF) — these are common reference points.

Does CSS use RGB or HEX?

CSS supports both. rgb(255, 128, 0) and #FF8000 produce identical results. HEX is more compact; RGB is more readable. Use RGBA for transparency: rgba(255, 128, 0, 0.5) for 50% opacity.
