It's a single paint color - the variance in light and shadow naturally makes color appear different, which is why basing a paint color for your home on a photograph on a computer of someone else's home is ill-advised.

In this room, it could be the effects of the lighting. However, to achieve a similar look using paint, try a metallic paint or iridescent glaze. Dutch Boy has a product that can be tinted in a variety of colors. Here is the link: http://dutchboy.com/products/interior/wall/special-finishes/metallic/index.jsp
