Which part of Clairol Nice'n Easy is the un-mixed colourant ?

Well I just bought Clairol Nice'n Easy in shade #79 (dark brown) and it says to used the un-mixed colourant as an allergy tester (it is non permanent) but it came with instructions gloves and cap , and a conditioner, a mixed colourant but no un-mixed is the conditioner the un-mixed colourant ? xxx Thankyou Lizzieee
