Grep on color lines

I wrote a simple PHP shell script that parses files and displays a specific element.
It generates a lot of output. In different colors (bash), green for OK, yellow for warnings, red for errors, etc.

During development, I want to filter out some lines. For example, all lines containing red text.

Can I use a command grep(or another) for this ?

I have no idea what your input looks like, but as a proof of concept you can filter any lines in lsoutputs that use green:

ls --color=always | grep '^[\[01;32m'

. , ^[ Ctrl-V Esc ( Ctrl-V Ctrl-[ ). , grep, \x1B ,
