Method

Three-digit HEX values are expanded by repeating each digit, then each red, green, and blue byte is converted from base 16 to a decimal channel from 0 through 255.

Worked examples

• #FFFFFF → rgb(255, 255, 255).
• #000 → rgb(0, 0, 0).
• #2563EB → rgb(37, 99, 235).

Privacy

The color value is processed locally in the browser.

Limitations

This version supports opaque 3- and 6-digit HEX colors. Four- and eight-digit alpha-channel HEX formats are not included.
