I just got the Carolyne Roehm Presentations e-mail this morning, and she's now doing wedding accessories, such as favours and gifts, wrappings and other yummy things. Her colour combinations are brilliant and include Navy and White, Silver and White, Lilac and Green and my favourite, French Blue and White.
Carolyn Roehm's site had some beautiful Limoges plates, rimmed in gold, and with a white linen napkin. Think of how stunning this would be with loads of crystal and silver!
Cath Kidston uses this colour in some of her fun oilcloths and in her furnishings. It's a classic colour, and works well with crisp white or a pale yellow. Think some of the Provencal prints.
Williams-Sonoma has the Kitchen-Aid MixMaster in a lovely blue that they call cornflower. I would love to have this (just to have on the counter, it's not like I'd actually USE it or anything).
I think that French Blue is just a perfect colour for the spring and into the summer.
