if (message.guild.roles.cache.find(role => role.name == "#Red")) return false; // The role already exists.

message.guild.roles.create({ // Creating the role since it doesn't exist.
    data: {
        name: "#Red",
        color: "#ff0000",
        permissions: 0
    }
}).then(role => {
    message.channel.send(`Role \`${role.name}\` created!`);
});
