What about this? the plant selector on the rhs site is quite good for ideas as you can tailor the search quite well. There is also a similar plant selector on the Crocus website. Berberis is lovely but not evergreen and depending on where you are the berries can also disappear quite quickly - ours always did but we are in the midlands.
The Eleagnus species are quite attractive and there is quite a choice from golden, cream and silver variegated leaves. They are also fragrant and some have berries - I think most of them are quite tolerant of dry soil.
Dogwoods wouldn't be evergreen but their stems would stand out well against the green background?
Hydrangeas are very thirsty so other shrubs may be more adaptable as long as you keep an eye on them in their first season.
