Tuffle or biscuit would work IMO. My preference is not to go with a dark brown sink. I love dark brown wood and have it in my kitchen but to me on a sink it just doesn't look right. Our quartz is lighter that your granite slab but I think I'd still choose biscuit because I prefer a lighter color sink (helps make the room feel lighter and brighter but that's my personal preference). We've had no problems with staining but also don't have kids in the house and clean up after every meal.

I didn't see purple in the tiny chip at the plumbing supply store. If you contact Blanco, they'll send you some small chips of those colors. It doesn't quite sub for seeing an entire sink, but I found my metallic gray sinks were very accurate to my color chip. Truffle is definetly less gray. More mushroomy.

This is a very old post but hoping to bump it, as I have the exact same question - does the drainboard for this sink fit over a dishwasher?

I'm so glad to read that everyone loves their SG sinks! I have put 3 in our new house ... moving in a couple weeks. I thought seriously about the BlancoPerforma, then talked myself into getting the 1 3/4 sink instead for the kitchen. I did get the super single bowl for the laundry room and have used it a few times already. How do you get the scratches out of it.... just some gray lines at the very top, maybe where the granite people scratched it. Warmfridge... I'm glad you are loving your tall counters. My kitchen bases are 39.5in and my laundry 40.5in. I can already tell my back is going to love it! I'm 5'7" and everyone tried to talk me out of doing taller bases for "resale" reasons. I didn't build to resale, so it will be our kids problem to find a tall buyer... LOL!
