I don't think that's the same thing, priyanhere. From the perlre manpage:

{n,m} Match at least n but not more than m times

Thus your example would also match 4 or 5 digits. Since we're looking for exactly 3 or 6, and those happen to be multiples, you could try this:

/(#([0-9A-Fa-f]{3}){1,2}\b)/

This is good, but below is more efficient /(#([0-9A-Fa-f]{3,6})\b)/
