there are a few (like selection blue shades in main canvas/views; recording red shades; red play-head and punch, blue edit-head/tail, green loop v-lines, etc.) that are simply hard-coded and thus fixed: you're not supposed to change that whatsoever. sorry
meter levels are also customizable but only through View > Options... > Display > Meters
what items are you possibly talking about?
