Tile Experts...Statuary Marble looks GRAY after thinset
First time remodel for us and first time poster here. Any advice would be much appreciated.
We are in the process of installing statuary "white" marble into our new addition bathroom. About 5 days ago, our contractor applied white thinset versabond (sp?) (not premixed but from powder mixed with water on site). After completing several rows it looks like a dark/dreary depressing gray - not the white with gray veins I envisioned. Some tiles look completely gray. Is this just because it still needs to dry out more? It's been 5 days already. I'm wondering if this is just the nature of our marble and that we just got a bad lot.
It doesn't seem normal to me because our tile looks pretty white when it hasn't been wet.
Here are some pictures under different lighting:
Please tell me I just have to be patient and wait for the thinset to dry more. This is our first remodel and I'm very nervous. Thanks for any advice.
