Sets the led trigger. A trigger
is a kernel based source of led events. Triggers can either be simple or
complex. A simple trigger isn't configurable and is designed to slot into
existing subsystems with minimal additional code. Examples are the `ide-disk` and
`nand-disk` triggers.
Complex triggers whilst available to all LEDs have LED specific
parameters and work on a per LED basis. The `timer` trigger is an example.
The `timer` trigger will periodically change the LED brightness between
0 and the current brightness setting. The `on` and `off` time can
be specified via `delay_{on,off}` attributes in milliseconds.
You can change the brightness value of a LED independently of the timer
trigger. However, if you set the brightness value to 0 it will
also disable the `timer` trigger.

Sets brigthness of leds in the given group to the values specified in
color tuple. When percentage is specified, brightness of each led is
reduced proportionally.
Example::
my_leds = Leds()
my_leds.set_color('LEFT', 'AMBER')
With a custom color::
my_leds = Leds()
my_leds.set_color('LEFT', (0.5, 0.3))
