If the Night Lords are super-edgy 80s Batman clones in 40K, what would be the equivalent of a super-campy 60s Batman clone in 40K?
Marines only work in metallics/matte industrial tones to push the "nuclear powered human shaped tank" aspect of the armour, heraldic primaries to push the "crusading knightly orders in space" schtick marines have, or precious metals to push the "god-emperor's immortal angels of death angle".
Anything else looks like clown vomit and brings out the worst elements of the physical design.
I agree totally, and this was exceptionally well put.
I think they are just going for fun/concept
I suppose the Chapter Master would be in a somewhat sexually tense situation with a Felinid thief, and the Marines would be largely responsible for cleaning up the crime-filled streets of the Hive World of Gotham, working closely with the loyal Commisar Gordon.
Bonus points if the Marines and Scouts manage to maintain civilian identities despite being eight foot tall supermen.
Seems like we're going full cheesy. We need the 1960s TV show Joker up in here.
Don't forget Kharn as Bane, Asdrubael Vect as Scarecrow and a generic sleazy Imperial noble as Penguin.
Don't forget the mastery of disguise of the Alpha Legion.
The Riddler is a Greater Daemon of Tzeentch, and a remarkably benign band of Harlequins are their Jokers.
But what would we name the chapter? Their motto? How do we explain the vastly different color schemes of the Battle-Brothers and Scouts?
