You could try a darker silver ,gunmetal, and lighter red on the bottom. What makes bmw gurus paint scheme work is the strong contrast between the orange and black. The silver and red in the photoshop works but its just more subtle and real paint looks a bit different. A dark transition color, think stripe, between the two could also bring out the effect.
