seatbelt question

i just swapped my interior out to all black and well the seatbelts were the onlything i dont have... i need black vert. seatbelts and they are hard to find so does anyone know if its possible to dye the fabric black? i have black hatch back seat belts could i take the belt out of the retractor and swap the belts into the vert retractor? i went ahead and changed the seatbelt plastic covers to keep up w/ them also changed all the recipticales. another idea i had but not really favoring it is i could just put a black harness in it but dont want that look + its a daily driver car, anyone know some comfortable harnesses that work w/ stock seats? just a thought
