Like Lyn, I tend to like the effect on myself better when there is also some light coloured item elsewhere in the outfit (not necessarily the same colour). But my hair is short so there is not that much of it -- maybe that plays a role.
Also -- I think it has to do with the level of contrast that suits you and that you enjoy wearing. Angie can wear higher contrast looks; Lyn prefers more tonal neutrals, so a high contrast shoe/ pant isn't really her thing. I think I am somewhere in between. Based on my colouring alone, I shouldn't really go high contrast. But my personality can manage more contrast, so sometimes I enjoy the effect.
For me, gold, taupe, animal print (snake print with taupe in it, or leopard) are all great bookending colours. Pewter doesn't literally bookend, but it does act as a sort of "shiny near-nude" and seems to lend cohesion in a similar way. I haven't really tried plain cream or white footwear yet. My hair is darker than Angie's so I don't think these will bookend precisely, but they might work rather like the pewter does. I do enjoy two tone shoes with navy/ black and cream or white. Actually, I LOVE them, as it is a safe way to introduce high contrast!
