Hair Coloring from Blonde to Reddish Brown?

I had my hair dyed blonde for sometime now and I want a change. I want to go darker. So my question is what would be the best color to use to go dark? I don't want to go dark brown or black but maybe a reddish brown or an auburn color. Any suggestions? Also would it be ok to dye my hair at home with a reddish brown color than go to the salon?

If you are going to do it at home , use a shade lighter - light warm or red brown. You will get a medium warm (red) brown. Follow the instructions in the box, start at the back and work to the crown and sides then the top. Do not put on the ends until the last 5-10 min. Wet the hair and suds the color and rinse well.. make sure the scalp is rinsed well . Towel dry gently and apply conditioner to the ends and put a cap over it and leave 30 min. Rinse with tepid or cool water.
