RGB color value of plotyy purple bars

I went to this page to determine how to overlay a line plot on top of a bar plot with multiple y-axes:

http://www.mathworks.com/help/matlab/creating_plots/overlay-line-plot-on-bar-graph-using-different-y-axes-1.html

However, neither the site or use get( b, 'Color' ) gave me an answer. In fact after using:

[ ax, b, p ] = plot( x, y1, x, y2, 'bar', 'plot' );
get( b, 'Color' )

I only got the answer 'flat'. I like this particular color of purple and was just wondering what the RGB value is for it.

If you are referring to the color of the bars, then they are the first color in your colormap

cmap = colormap();
cmap(1,:)

On my system with the default colormap that is [0 0 .5625]

Try

get(b, 'EdgeColor')
get(b, 'FaceColor')

With Matlab R2012a, I get black bars and get [0 0 0] for EdgeColor and 'flat' for FaceColor.
