How to add color coding to boost::log console output?

Question

I\'m trying to add colored log output for boost::log under linux. I read the following and I tried this:

#define MY_LOG_ERROR() BOOST_LOG_TRIVIAL(error) <<

I've recently done this with a simple custom sink backend

coloured_console_sink.h

#pragma once
#include 

class coloured_console_sink : public boost::log::sinks::basic_formatted_sink_backend
{
public:
    static void consume(boost::log::record_view const& rec, string_type const& formatted_string);
};

coloured_console_sink.cpp

#include "coloured_console_sink.h"
#include 
#include 
#include 
#include 
#include 

WORD get_colour(boost::log::trivial::severity_level level)
{
    switch (level)
    {
        case boost::log::trivial::trace: return 0x08;
        case boost::log::trivial::debug: return 0x07;
        case boost::log::trivial::info: return 0x0F;
        case boost::log::trivial::warning: return 0x0D;
        case boost::log::trivial::error: return 0x0E;
        case boost::log::trivial::fatal: return 0x0C;
        default: return 0x0F;
    }
}

void coloured_console_sink::consume(boost::log::record_view const& rec, string_type const& formatted_string)
{
    auto level = rec.attribute_values()["Severity"].extract();
    auto hstdout = GetStdHandle(STD_OUTPUT_HANDLE);

    CONSOLE_SCREEN_BUFFER_INFO csbi;
    GetConsoleScreenBufferInfo(hstdout, &csbi);

    SetConsoleTextAttribute(hstdout, get_colour(level.get()));
    std::cout << formatted_string << std::endl;
    SetConsoleTextAttribute(hstdout, csbi.wAttributes);
}

usage

typedef boost::log::sinks::synchronous_sink coloured_console_sink_t;
auto coloured_console_sink = boost::make_shared();

boost::log::core::get()->add_sink(coloured_console_sink);
