strawberry blonde hair color/or halle berry hair color

Hello!!!

I have been interested in coloring my hair strawberry blonde
and/or halle berrys hair color. I have tried Ultress bright red to get it brighter than my natural dark brown color and it has changed to like a mahony or sienna color. So now that it is this color it is not too far from getting the color that I want. Should I mix two colors like a red and a blonde? or go to a salon? I really don't want to spend a lot of money coloring my hair. Any suggestions. Wrtie soon. Thanks
