How do I remove parentheses using sed?

input (192.168.1.1)
output 192.168.1.1[COLOR="\#738fbf"]

2 
echo '(192.168.1.1)'   | sed 's/)//;s/(//'
3 
echo '(192.168.1.1)'   | sed 's/[()]//g'

Thanks guys, but I have a problem using this in awk code, is there a way to pass this in a print statement in awk?

For example

awk '{
if ($1 ~ "^[(0-9]+\.[0-9]+\.[0-9]+\.[0-9)]+$" )
{print `sed "s/[()]//g"`'${1}'}
}'

The above code does not work. Basically the logic checks to see if the first field in a txt file is an ip then print out the ip stripping the parantheses.

Thanks!
