We just got a Marquis spa...without the longer version of the story, our first tub was the Bronze color (antique bronze?). I liked it, but my first choice was the taupe granite, however that would have taken longer to receive. Due to some problems, we were provided with a new tub...this time in taupe granite. It is beautiful. The base color, and also the majority of the cover is off-white. There are brown and grey flecks throughout. It shows off the light beautifully!
Another reason I'm happy with the granite finish is that it doesn't show the water spots like our previous tub did.
If you would like, I can try to take a photo and email it to you. We only have the standard lighting. I'm not sure if you got the LED type light....
Private message me if you would like me to send a photo....
