if - elif

instead of the if - elif statements, use dict.get(key, default):

formatting = {
    1: Color('{green}[GOOD]{/green}'),
    2: Color('{cyan}[INFO]{/cyan}'),
    3: Color('{yellow}[LOW]{/yellow}'),
    4: Color('{magenta}[MEDIUM]{/magenta}'),
    5: Color('{red}[HIGH]{/red}'),
    6: Color('{red}[!!CRITICAL!!]{/red}'),
}
leader = formatting.get(severity, '[#]')

String formatting

if you use Python >= 3.6, use f-strings.

And instead of the long list of arguments, split it up in lines. I would at least refactor the strftime("%H:%M:%S", gmtime()) into a variable called time:

message = f'[{time}] [{self.domain}] {leader} {message}'
print(message)

if you also have to serve pre-3.6, this solution:

format_args = {
    'time': strftime("%H:%M:%S", gmtime()),
    'domain': self.domain,
    'leader': leader,
    'message': message,
}
template = '[{time}] [{self.domain}] {leader} {message}'
print(template.format(**format_args))

can help you limit the line length, while keeping the template clear.
