Carpet Colour

[Khurram Darugar]

This may be a commonly known question, but does the carpet color need to match the interior color?
I have bamboo/rust leather and a similar carpet color and its a bit intense.  
I was thinking of changing to the carpet to square weave medium grey with matching grey lining (car is painted silver DB 180)?
Generally speaking the car is ok good condition and short of the 15 inch alloys and looks pretty stock.      

I guess my query is is this just going to look way off, or can I get away with it, my interior while nice is a bit too orange?
Thanks
