Expression bar CummeRband Colours

Question

[V]

Hello,

I'm using CummeRband in R to plot some expression bar charts, using the following.

myGenes<-getGenes(cuff,myGenesId)

gb<-expressionBarplot(myGenes,showErrorbars=FALSE)
gb

and this outputs the barchart with all my samples and their FPKM values but the colours are terrible, and I can't figure out a way to change them. Any suggestions on how I can modify the above code?

Thanks
