my hair colour is somewhere between dark blonde and light brown. I bought 2 bottles of semi pernament wella dye (one dark blonde and the other light brown) and I mixed them both together 50% of each exactly and then applied it to a fading piece. I left it on for 30 mins and then rinsed it out - however now it has a red tint to it - does anyone have any suggestions on why there is a hint of red. Could it be that I left it on too long or should I have mixed the dyes differently like 25% of one colour and 75% of another colour etc... Anyone ever mixed the back 2 natural dark blonde with the back 2 natural light brown leave in conditioner - does it give the same hint of red. Any suggesitons will be greatly appreciated.

Best Wishes

Dan
