Thank you, your regex looks indeed a lot more concise. I am getting the error message that the -r option is not recognised:
Code:
# sed -re 's/#[0-9a-f]{3}|#[0-9a-f]{6}/\U&/' main.css
sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
       sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]

What is the purpose of the -r option and how do I fix this in this case? I am running sed on FreeBSD 7.1.

NAME

       colortest-python - Display color test chart and convert between color values

SYNOPSIS

	 colortest-python

DESCRIPTION

       Displays 256, 88 and 16 color tables depending on what the terminal supports. Also provides for conversion between 256 and 88 color values.

       The program automatically detects 8, 16, 88, 256 color capabilities (via ncurses) and displays the appropriate color charts. Program can
       display the colors as blocks or 2d cubes optionally with color values overlaid in int or hex values, it can show the full rgb text string
       and show the display with a vertical (default) or horizontal orientation.

       In addition to the color charts it can also convert between 256 and 88 color values. This can be useful when converting various terminals
       like between urxvt and xterm-256.
