"When the Dragon Ball Z anime was released, a filler scene in the episode "Goku's New Power" was added showing the Super Saiyan as what looks like a Great Ape with yellowish colored fur instead of the standard brown"
Later in the non canon Dragon Ball GT we saw a more detailed version of a golden great ape, plus "The GT Perfect Files note that the Golden Great Ape form appears to be the Super Saiyan form from the legends, further implying that the original Super Saiyan utilized the Golden Great Ape form."
Was the original super saiyan a golden great ape in canon Dragon Ball?
