That seems to be happening for me automatically.
I did a cluster analysis and chose Color Clusters from the red triangle menu.

Then when I choose Analyze -> Multivariate Methods -> Principal Components, the Summary Plots and Biplot are colored by the clusters.

Can you give us some more details on what you've tried and what plots aren't colored as you'd like?
