Like you guys, I think they should have kept it silver, with her original hair colour. It's extremely annoying that the live action film now has her blonde and in a blue gown as well; at least Maleficent kept her original costume for the Christening scene (minus the purple inner sleeve colour), and you can see they've adapted from her original animated outfit in her other costumes in the film.
Maybe it was changed from silver in the Princess line as it looks too much like a wedding gown ? Just a thought.
I don't mind that they changed the costumes so much for the live-action Disney Cinderella
. Seeing new costume designs is a joy. I just wish Cinderella's was more impressive, is all. Like the Mattel doll's. I think I would love if they made the costumes a lot more like the originals like Maleficent's in the christening scene in Maleficent
, but I love them as they are, too.
If Cinderella's dress was a slightly bluish silver instead of white, I don't think it would look like a wedding dress.
Yes, her dress looks blue in that shot cause they are supposed to be in (relative) darkness, and under the night sky, so everything has a blueish tint. Look at the prince's top: it's supposed to be white, but in this shot it looks light-blue...
And look at their skin color... they are definitely in darkness.
You and Atlantica
are quite right that it is the lighting that makes Cinderella and the Prince look like they are wearing blue. Actually the prince's jacket is a yellow or gold, as you can see by this picture I took from the original film:
