The problem is, how do you define inverse?  A couple of simple rules might

r <- 1 - r
g <- 1 - g
b <- 1 - b


h <- h + 120
s <- 1 - s

but not matter what [smooth] rule you pick, there is a colour which is
unchanged by the rule.  There will also be a set of colours which are
nearly unchanged by the rule.  These come from the fixed point
theorem(brouwer).  You could make a non-smooth function, but it would
probably look ugly.  To see this, think about what you would do on a
gradient from white to black, then try your rule out on a gradient from
white to black via some primary colour.
