I made the Pink M4 recolor for HomelessWitch per request.
The Gold M4 is made, and it has a Gold Riot Shield with it.
I made the Gold Souizen for MysticalDragon per request.
I made a Rainbow PBP Shotgun for Milkshake per request.
Any recolor of a gun you see (with the exception of gold M4/riot shield) is made a staff member, whether they get auctioned off or not is up to them.
