After reading all your comments I understood what you were saying. I think Samsung has changed the design. I suggest you to visit offline stores like Samsung stores, or other affiliated stores like Croma, reliance, bajaj etc. You may find the older versions of this adapters if they have the old stock.
I've gotta say that you have a keen observation. Even I have the same adapter you're searching for but in black color. I went and checked the website and then i got to know about the new design which us now for all the adapters.
