Common RGB to Hex Conversions

How it works

Enter RGB color values as three numbers (0-255) for red, green, and blue channels. Use individual input fields or paste values in common formats like "255, 128, 64" or "rgb(255, 128, 64)".

Each decimal value is converted to its 2-digit hexadecimal equivalent. Values less than 16 are padded with a leading zero to maintain the proper 2-digit format for each channel.

A live color preview displays the exact color represented by the RGB values. The hex output is provided with and without the "#" prefix, plus CSS-ready formats. Copy any format with a single click.

What to Know Before Using

RGB range: Each channel ranges from 0-255 (8 bits). 0 means no color, 255 means full intensity of that channel.

Hex format: RGB converts to #RRGGBB. Each channel becomes 2 hex digits: 0-15 becomes 00-0F, 16-255 becomes 10-FF.

Additive mixing: RGB is additive color. Red + Green = Yellow, all three at max = White, all at zero = Black.

Alpha channel: Standard RGB doesn't include transparency. For RGBA, add a fourth value (0-255 or 0-1) for opacity.

Color accuracy: The preview shows colors as your display renders them. Calibration affects actual appearance.

Common Questions

What is RGB(255, 0, 0) in hex?

RGB(255, 0, 0) is #FF0000 - pure red. 255=FF, 0=00, so red=FF, green=00, blue=00.

How do I convert RGB to hex manually?

Divide each value by 16 for the first digit, use remainder for second. 200÷16=12(C) R8, so 200=C8. Or use a calculator for speed.

What RGB makes white?

Pure white is RGB(255, 255, 255) or #FFFFFF. All channels at maximum intensity produce white in additive color.

How do I include transparency?

Standard hex doesn't support alpha. Use 8-digit hex #RRGGBBAA or CSS rgba(). For 50% opacity: rgba(255,0,0,0.5) or #FF000080.

What color is RGB(0, 0, 0)?

RGB(0, 0, 0) is pure black (#000000). No light from any channel produces black in additive color mixing.

Can I convert from CSS rgb() format?

Yes. Paste "rgb(255, 128, 64)" directly. The converter parses CSS color formats and extracts the RGB values automatically.

What's the hex for gray?

Gray has equal RGB values. Medium gray is RGB(128, 128, 128) = #808080. Light gray might be #CCCCCC, dark gray #333333.
