> don’t use more than 16 colours We aren't in the '80s. Use true color if you want to, modern terminals should support it (built in Linux tty is a weird outlier that should have supported true color years ago). But that also depends on the context. For example if something implements its own TUI with a lot of elements - it makes more sense to use more colors than the barebones set. Most programs that do care about colors, check what terminal capabilities are before using them.
