While I didn't love the toothpaste at first, it was at least a big upgrade on the previous green and I think it has actually stood the test of time pretty well.

I can definitely see how it could be improved. Unfortunately, I expect they'll take it in the other direction, because it will probably match the ugly look they've given the 787/777 interiors, MLLs, etc. Which is too bad, because when those brown and grey planes start flying around, they'll immediately look dirty and dated.
