Yeah, some non-colorblind people mistakenly think we can "fix" it by mapping trouble colors to different colors because they fundamentally misunderstand that we always see like this.
In other words, colors assigned to good/warn/error icons can be shifted almost arbitrarily as long as they are consistent over time for one person, but it backfires if you're doing the same shift for colors in a picture of a tree's spring/autumn/fall leaves.
