When I use gnuplot v.4.6.3 (Win7) to plot multiple data sets separated by double blank lines via

pl 'Data.out' i 0:300:5 u ($1):($2):(column(-2)) t 'profiles' w l lc variable lw 2 

I get a chart with a suboptimal sequence of colors (for example, blue, yellow and green) for subsequent data sets.

How to assign specific colors, such as 'black', 'red' or 'blue' to various data sets?

Also, how to assign different labels for the various colors?

Thanks for any help.
