Walker Evans spring colors

Anybody know the specific color/ weight ratings for the WE shocks/ springs? I just bought a set of WE shocks (supposedly from a 13 800) and they came with gray/ 225lb rear, and gray 200lb front springs. I’d like to go up to 250 rears, and maybe down to 175 lb fronts if I can find them, but I can’t find anyone that lists only the springs and their ratings.
