That's good new,
My floaters are mainly gray and blackish but i do have that annoying one which i always see, when looking at computer screen and when outside in daylight :( that one is yellowish greenish lol I have always had floaters since i was little, but they where the little black dot ones and only visible when looking at a blue sky. Never worried then, of course that's when i never had HA so it never crossed my mind.
I hate this horrible anxiety :(
