I'm with Ron on finding a complimentary colour... adds contrast.
Although, saffron coloured on top of something dark would likely look neat (or harsh...I don't know personally, these are just thoughts). I am hoping to buy red flashes to go with a handful of kilts... complimentary/contrasting for my Gordon modern kilts, it'll match my Ulster, and my Muir, and my Gordon red, and not clash with my weathered Lamont (lots of neutrals in there). That's just how my thought process goes.

You could always get strips of cloth, and tie it in a bow knot, and then fold your hose over it. Not entirely an inaccurate way to do things.
