What this calculator does
This tool converts an RGB color (red, green, blue channels, each from 0 to 255) into its 6-digit hexadecimal (HEX) color code, the format used in CSS, HTML, and most design software (e.g. #0080FF).
How the conversion works
Each of the three RGB channels (0-255) is converted to a two-digit base-16 number. The three two-digit hex pairs are joined together to form the final 6-character HEX code, prefixed with a #.
- 0-255 in decimal becomes 00-FF in hexadecimal
- Example: RGB(0, 128, 255) becomes #0080FF
This tool is intended for general design and educational reference.
