We have similar, if not identical tiles in the guest bathroom. The vanity came with a top that has multi color flecks in it, but to me, it reads pink and I couldn't stand it!! To cool the pink down I ended up using Valspar Frappe. In our lighting it looks grey with a ever so slight green undertone. It really helped, and so did using brushed nickel towel rings, tp holder, faucet, ect. I decorated with little touches of green and white to further reduce the pink feeling.

I used Valspar Timber Dust first, it was a beige-ish color but it made the pink stand out. Brown does the same thing! I feel your pain!
