Paint Colors for Kitchen and Hall?

I am looking for paint colour ideas for a kitchen. The kitchen is big with light oak kitchen unit and oak doors and skirting.

I would also like ideas for the hall and landing colors. The hall and landing have plenty of light with oak stairs and oak doors and skirting. One wall runs from the hall downstairs right up to the landing ceiling upstairs. I was thinking of doing this wall in a darker colours than the rest?
