30 may be out of range again, but your point is exactly right.

None of these color palette sites & service ever work for actual interface or brand design work. They encourage picking harmonic sets of 4-5 colors, which is only a secondary parameter when actually designing - you need contrast & workable combinations first and foremost, while you seldomly really want more than two different hues (unless you know what you're doing with them).

I consider offers like this a nice starting point, get an impression of different ranges. But even if I end up picking a set from there, I'll seldom be using all of the suggested colors in a set to build my palette.
