Yellow Guardsman?

Hello fellow Guardsman,

I want an interesting colour sheme for my Cadians.I thought about using a white primer, with the airbrush magenta in the shadows and then imp fist contrast. The cloth would be the same as the boxart. What’s your opinion on the sheme, or is the classic look better? I sadly don’t have a guardsman around to test it. Also I would need to buy the paints. Wold love some opinions
