python – making a discord bot print coloured text using the css code format

Hi i have a simple bot that takes a command:

@bot.command(name='repeat', help='help me to understand bots')
async def test(ctx, *lines):
    print("repeating")
    coloured_lines=()
    for line in lines:
        coloured_lines.append("```css n"+ line + "```")
    await asyncio.gather(*(ctx.send(line) for line in coloured_lines))

You write to it a command like $repeat “green text is cool”, and you should get an output like:

instead you get enter image description here. My intuition is that this is because something is happening with the ` character – although i am not sure what, or how to fix it.
