How to get ROOT 6 Colour Palette in ROOT 5?

[machiel]

I maintain various machines, and I have got ROOT 5 working on all of them. For one machine I have got ROOT 6 too, which seems a nicer version and has a much nicer Colour Palette for 2D histograms. I think it’s called kBlueYellow. However, this pallete (kBlueYellow) is not known in ROOT 5.
How can I set a colour palette in ROOT 5 that resembles the one in ROOT 6? (I could install ROOT 6 in all other machines, but this will take time)
