Creating new ColorFunction / ColorDataFunction

Dear all,
I'm putting together a package to automate some of the specific time 
series and bar chart styles used by my employer. Ultimately I hope to 
be able to set it up as a palette/package combination to provide a GUI 
that can used in Player Pro. 

There are many things I am still struggling with. One of them is how to 
define standardised indexed color schemes different to the ones that 
come built into Mathematica. The idea is that users could choose one of 
our standard sets of colors in a (say) ColorScheme option to the 
XYZLineChart and XYZBarChart functions I have written, where XYZ is the 
acronym of my employer, which you can probably guess by Googling.

In other words, what I'm looking for is a way to define XYZColors[n] as 
an indexed color scheme, so that:

XYZLineChart[data, ColorScheme->XYZColors[3] 
PlotStyle->{Directive[AbsoluteThickness[2],Dashed], 
AbsoluteThickness[1]}]

results in 

DateListPlot[data, Joined->True, PlotStyle->{Directive[XYZColors[3][1], 
AbsoluteThickness[2],Dashed], Directive[XYZColors[3][1], 
AbsoluteThickness[1]]  }  , 
multiple_other_options_defined_in_XYZLineChart]
