Gin
Gin's basic skin would be the profile pic I have. Black scarf, Silver long coat and twin swords. The Palette swaps would change his coat, scarf and sword colours, using Red, Black, Yellow, Green and White, referancing some other characters of mine, yellow referencing Sam. The coat and sword would change to the corresponding colours, while the scarf would darken or lighten depending on the colour.
Sam
Sam's basic skin, again, is his profile pic. a white lab coat with a yellow shirt and black trousers. Pallette swaps would change his coat and top, using Grey, Silver, Black, and Red, (Grey referancing Cobalt and Silver referancing Gin) as well as one that gives him brown hair, glasses and a black top, referancing Machin Raal
