Ellen I just bought another box of the same color and did an all over colour again. And that's how it came out. Still doesn't look like the colour on the box, but it's better then before
Are you going to keep it this color? It looks good but I know it can bug you if it isn't what you wanted. Did they show the color for the color your hair was before the change? Reds be so tricky.
It could be the base color. It should be noted on the box. They seldom come out like the box though. Maybe a different base color will cover the purple.
