Wintersong - that pergola's looking great.
I use bright greens and variegated plants to stop white looking flat. You can add a bit of deep red and some yellow/gold or plum coloured foliage plants to lift the purple and white too. If you like Phormiums they're good for a contrast in shape and foliage colour. Foliage contrast is the best way of lifting a colour scheme - for big leaves - I like Ligularias , Fatsias and Hostas , and for a vertical contrast- Foxgloves, Verbena bonariensis, Alliums etc to give height and stop everything looking a bit samey. I find plants like Euphorbia are good for linking colours - the bracts are a good contrast to the foliage so you can have two plants nearby picking up the two different colours.
