How to describe this color blonde...

My natural hair is light/medium brown and I haev an appointment to go blonde.  I alway alternate between the two colors.  My dilema is that I can NEVER get a hairdresser (and I've been to a few) to get my color right.  Recently my hair started picking up a golden/yellow/orange/red tone when it's dyed blonde.  I stress to the hairdresser that I do not want any golden/yellow/orange/red tones but somehow I still end up with them.  Here is the color I'm looking to get to and this is how I'd explain it...please tell me what I'm saying wrong:  I want honey ash blonde foils w. a few highlights of a darker ash blonde.  How would you describe it?
