My roots are growing out, dark brown, the part of my hair is Light brown with lots of blonde highlights, I would like touch up the roots but don't know what color to use. Any recs are appreciated. TIA!

Here is an example of what it looks like right now. (LOL - not me in the pic but hair color is very similar)

Personally I think that picture of that ladies hair is quite nice! Did you know that this type of hair colour is in fashion now? The kind of grown out look with lighter ends is definitely in at the moment! But if its driving you mad you could colour it all one colour with a shade darker than you natural hair colour, that should give it an even colour all over but you might find that the blonde parts that get colour will wash or fade quicker because its so light or if you want your highlights re-done then you should go back to your hairdressers and get it done professionally,
