I flyfish and tie my own flies, So I use a bunch of different materials that I have. But you could go to a flytying shop and pic some up for cheap. It all depends on the territory, but in the woods I use a piece of artic fox, which is snow white. In the fields a crows wing, and it stands out like a sore thumb. But for a mix up in either situation some red, yellow, or orange marabou feathers from a fly shop work really well. And they move with the slightest wind. Caught both my cats this year with black and yellow marabou attractors. Hope this helps.
