Hi Sandra,
White flowers are never very frolific for some reason Duchess of edinburgh I think is a white clematis but a really weedy plant. what you could do is grow a white shrub rose up your arch taking it up a bit at a tiem & it will frame it nicely then you could leave the hips on for the birds/autumn colour ( not really blue or white though)
Failing that there are some stunning blue (ish)clematis
