How it works
Hex digits, optional prefix
Each digit is selected from 0123456789abcdef. Length counts the digits, not the optional # prefix. Generate between one and 10,000 rows within the total output cap.
The prefix is handy for color-like values, but CSS accepts only specific hex color lengths. A hexadecimal string by itself is not automatically a valid token or identifier.
