Mostly my parachutes are tied with white wing posts, but I do also use fl. orange on some and I also use Light Dun for the posts on my blue winged olives. As far as the material for the posts go, I strongly prefer turkey flats or turkey T-base feathers. I'm not a natural material purist by any means, but I do like the look of the natural material as opposed to synthetics such as anton or Hi-Vis. Between the turkey flats or T-base feathers, I do slightly prefer the T-base to the flats as the tips seem a bit more even to me, but they both work fine really.
