Here in Poland Honda offers the Jazz in 3 different white exterior colours: Taffeta White, Platinum White Pearl and Premium Sunlight White Pearl.
Taffeta White is solid white without extra cost, "cheap" and easy if additional spraying is necessary after a repair.
The pearl white colors are more expensive:
Platinum White Pearl costs extra 2500 PLN in Poland (about € 555,- / £ 465,-).
Premium Sunlight White Pearl costs extra 3200 PLN ( about € 700,- / £ 600,-).
We have chosen Premium Sunlight White Pearl. Beautiful, changes colour slightly depending on the (sun)light
Taffeta White is not available on the British website, but it is available on the German, French, Dutch etc. etc. websites. I have no idea where you live, but there is bound to be a Honda website where you can find the available colours (with prices) in your country.
Unfortunately, I don't think you will find versions and colors with a Ford diesel engine for you...
