Lol I'm pretty sure that nobody knows how the filter colors work with each other. For example, you can't just switch top filters from green to blue and expect "better" treble. The FR changes, the bass changes, the tonality changes. You really need to go through almost all the filter combinations if you are truly looking for the best sound for your ears.
I use gold lower and red upper on ACE because it sounds the best. But almost nobody would try gold lowers. Same for Titan, I tried going from red lower to purple in an attempt to slightly reduce the bass, but the entire bass range fell apart and the soundstage collapsed. Switching to grey lower sounded fine, but there was too much treble sharpness, so I had to go with a red upper, but that made the bass too boomy. 4 or 5 combinations later, I finally landed on red lower and green upper and found perfection.
Haha it worked someone's put me out of my misery Will try gold lowers with red/green.
