Hair color salon recommendations in/near West Seattle

I've been coloring my brunette hair either myself or at a salon for about 40 years(!). My hair starting greying when I was in my late 20s (thanks, Mom!). Seems like all the salons charge at least $150 plus tip. Can anyone recommend someplace that might be a little less expensive? I am 72 and just want a boring natural brunette. TIA!
