I know your looking for yellow but since you mentioned OD fire, you may want to look into OD enchi. It's not as yellow as OD fire but it is brighter and cleaner in my experience with both, it's just orange instead of yellow. Really nice combo imo, reminds me of a tiger lol.
One other thing, if your looking for a bright and clean yellow, I would stay away from pastel combos other than desert ghost. All the others I've seen are beautiful when young but as they age they tend to get dirty or brown up. I have a pastel enchi and although he is still beautiful, his top has become very dirty looking. He still has bright yellow sides but I believe that is thanks to the enchi. Most pastels start bright yellow but as they age they turn to more of a light brown look.
