I have a client who wanted 5.77 in clynol, so I used my old tube to test it and she liked how it came out, when I went to go and buy more tubes as mine wasn't enough for her long hair, they said it had been discontinued, I checked with her if I could use a 5.7 and red mixtone and they agreed and said it would be fine and I've also used it in the past and had come close to the 5.77 but this time is has come out more purple shade then red... Am I missing something... It's been fine when I've used it before x
