Thanks for the suggestions. Have decided against Willow, as have a few out the back, but I did see a nice Flamingo one.
I'm considering non-trees too, this is my current list, not sure if I have a favourite:
Viburnum × bodnantense 'Dawn'
Too much leaf shade?
Hamamelis × intermedia 'Pallida'
Stag's horn sumac
Euonymus europaeus 'Red Cascade'
Worried it might get a little wayward.
