## Gamuts

The conversion tool support three gamuts: Gamut A, B, and C, [documented here](http://www.developers.meethue.com/documentation/supported-lights). Use them as follows:

```python
from rgb_xy import Converter
from rgb_xy import GamutA # or GamutB, GamutC

converter = Converter(GamutA)
```

If no gamut is specified, defaults to Gamut B (A19 Gen 1 Hue bulbs).
