We have the brown sink and ORB faucet and bought the flange and strainer to match. With all the brown I felt like silver would have looked odd. Except for the sink grids we have no silver in our kitchen!

Anthracite bar sink, silver strainer and faucet

I too have ORB faucet with my biscotti silgranit sink and bought the color matched strainers as it gives a nice cohesive look

Do you need to buy the strainer baskets from Blanco or are there universal ones that fit? I'm planning to order the Blanco Performa with double bowl and I have a hard time thinking about buying two $59 strainers!

My sink is truffle and I have a chrome flange. My faucet is chrome too but I think the chrome would look just fine regardless of your faucet finish.

I bought a flange that matches my faucet from an outside vendor. I heard the Silgranite ones were not all that great
Cafe Brown with Antique Brass.
I would have to hunt the information on the vendor.

I had decided to go with the matching one from Blanco, but I found out the day of installation, my granite guy didn't order it along with my sink, because he thought it was too expensive! So, luckily I found an ORB one at Lowes and it looks good with my ORB faucet.

Hi,
Thought I'd already posted here. Guess not. Here's our bisquit sink with an off the shelf, from Home Depot, ORB flange and strainer.
Can't imagine having a different color than the faucet, unless it matched the sink.
Have fun!

Thanks for the picture, it is very helpful.

I have leathered black granite, anthracite sink and orb faucet, soap dispenser and flange. In the pic, the silver thing is not the flange, it is a strainer that goes with something else. The flange can kind of be seen beneath that.
