I've heard the rumors about the Jazz switching to black and white with yellow as an accent. From what the owner said is that "it won't be just black and white, but those will serve as the base." So not sure how yellow got added except for the Jazz game schedule.
But regardless i'm excited. They also said they will be getting a new logo (not sure if its just a recolor of their current or a new one all together).
I like the blue, green, yellow look they have now, but I do think its time to update their normal set since they've had since 2016.
