Well there are two things you could do:-

1) The quick way is to modify LOADCT. Add an extra COMMON block into
the code to store the table number then write a two line function to
return this value.

function whichct()

common lastct, ct
return, (n_elements(ct) eq 0) ? -1: ct

end

I'll leave it to others to dissuade you from this coarse. Though the
Lord knows there are many RSI routines which could do with being
written properly (MEAD, STDDEV, REFORM...)

2) The slow way is to reload the colour tables till you find a match

function whichct

oldquiet=!quiet
!quiet=1

common colors, r0, g0, b0, r1, g1, b1

if (n_elements(r0) eq 0) then return, -1

r=r1
g=g1
b=b1
for i=0, 40 do begin
loadct, i
if (array_equal(r,r1) and array_equal(g,g1) and
array_equal(b,b1)) then goto, finish
endfor

i=-1

finish:

!quiet=oldquiet
return, i

end
