I can't speak for everyone who interviews young attorneys. I can only say I would not find a dark brown solid grenadine either "offensive or distracting." If someone looks as if they've made a decent effort to make themselves presentable, to the extent I'd think about it at all, it would be a "positive." The other 99 and 44/100's of my attention would be on academic and professional background, skill set, ability to fit in the firm dynamic, etc.
I agree one should avoid distractions with the idea of having an interviewer focus on you and not on what you're wearing. I merely happen to think there's nothing about a solid brown tie that's going to detract from an interview.
It is neither but in the cases it gets noticed by the interviewers, the results could be polarizing - either they like it or they don't. That creates another unnecessary data point for their decision making progress that could potentially ruin an otherwise good outcome.
In my opinion, it is better to remove and reduce attributes that risk diverting interviewers' attention away from work competency and personality.
p.s., navy suit, white shirt, with shiny solid red tie looks like you are going for an presidential debate.
