You actually have a couple of tasks. First split your input up into sentences. That is somewhat non-trivial for a start. However, modules like Lingua::EN::Sentence help solve that problem. Once you have an array of sentences you can process each one by:

use warnings;
use strict;

my @sentences = (
    "This is  [color]some text[/color].\n",
    "This is a [color]test[/color] oops![/color]\n",
    );

s!\[color\](.*)\[/color\]!\[blue\]$1\[/blue\]!g for @sentences;
s!\[/?color\]!!g for @sentences;
print for @sentences;

Prints:

This is  [blue]some text[/blue].
This is a [blue]test oops![/blue]

Note the second pass to clean up any old markup that got left behind.
