I sort of get your point but when you look at Rune T and Saradomin armor side by side, there is a very clear difference, I do notice that the other trimmed armors all seem to have the same white trim though, perhaps a color change on those would be a better use of time.
Reverting the colors will make Zamorak armor look like rune trimmed dragon armor, Guthix will be rune trimmed addy, and Saradomin will be rune trimmed steel... this just may completely destroy the vvalue of any god armor but Zamorak.
I did a quick comparison of the 3 god armors vs trimmed and then looked at the 4 other trimmed armors and changed the white trim to better suit their metal type. The only one that looked natural was the Iron, I dont understand how black, mith, and addy all have white trim and rune has a dark cyan trim.
