Though my natural color is dark blonde, I have been using lighter shades of blonde with good results. My hair lightens easily, but the gray is harder to cover. I would like a light to medium blonde color with reds or orange. With the golden shades my hair tends to brassiness, so I usually stick with ash or neutral colors. I am thinking of ordering one each of the medium and light ash, neutral blonde and golden blonde. Then using just a little of the golden blonde and mixing the others to find the color I want. Will this work or any better ideas?
