pandas plot giving value error in IPython/zmq/pylab/backend_inline.pyc
Using ipython 0.13.1 and pandas 0.10.0, having both the 'color' and 'style' parameter to pandas.Series.plot() gives a value error in pylab. Not sure if I should report this here or in ipython?

``` python
from pandas import *
ts = Series(randn(1000), index=date_range('1/1/2000', periods=1000))
ts = ts.cumsum()
# having color and style causes Value error crash
ts.plot(color='#000099', style='b-')
```

``` python
ValueError: to_rgba: Invalid rgba arg "['#000099']"
need more than 1 value to unpack
```
