Saber Auras/Gif

Greetings All I am currently trying to expand my knowledge on making gifs with plugin Saber aura when I go to make the gifs on PS they come out downgraded, I know 256 pallet is all that is there for gifs but I could have sworn I have seen some artists make perfect gif

my project is based around Gohan turning into his ultimate form & also super Saiyan with colors dark blue background white. yellow, purple. green are only the main colors in my project so it shouldn't be to big of color grab but still I wonder because Ive done a few other projects in the past just doesn't turn out the same
