Currently the bb.init() function takes a bb10AccentColor as a parameter. The purpose of this color definition is for solid headers in grids and used as essentially a darker version of the bb10HighlightColor.

The accent color is also intended to be used to create dark-to-light gradients in the same color palette on some controls. However this same effect can be achieved by simply computing a darker shade of the highlight color like the bottom border used on the normal BB10 image list headers and the touch outline of a list item.

Removing this property will reduce the complexity of the init and also insure that the colors used in the app are in the same color palette for gradient and visual styling.
