You can’t go wrong with any color they all look nice, I have the white as well because it matches with my furniture. The official stool comes in January I think and I will Splurge on that for the look
I've just got the 6000 but I'm really disappointed with the pianos. Great design and features like the keybed maybe I just need to rely on a good VST and use it as a midi controller but then I'm better off buying something with USB audio. It's so bloody stressful finding the right keyboard. I'm also returning a Roland RD88 which I would choose over the Casio if only the the keys weren't so heavy.
