Personally, I wouldn't go get a new saddle. I would rather just switch up the pad because they are cheaper.
If you are into competitions and things like that, then I would go with a black/white zebra pad, get pink/black braided reins, and then get zebra and pink boots. Otherwise, just get the zebra pad and stick with all of the black and white. My saddle doesn't match my tack, either... it has a LOUD pink cancer ribbon painted on both sides. My colors are also black/white zebra.
