How to change the color of an existing discord role using discord.py?

Question

Python

I have a role. I want to change the color that the user specifies in it. How can I do it?
Code (example):

@commands.command(
        aliases=['role']
    )
    async def edit_role(self, ctx, role, color):
        role = discord.utils.get(ctx.message.guild.roles, name = role)
        await role.edit(colour=color)
        await ctx.send('Успешно!')

(PS I do everything in cogs, but I will be glad for any answer)

Answer 1

The bot can create a role
but not change it in any way
