Anyone got a good colour for modern brickwork? GW recipe please..
Yeah I know it's a stupid question 
Which brick are you after? There's at least a 1000 different ones in the UK alone

If you're painting "generic" red brick, based on the bajillion bloody housing models we do 95% of the time at work, I'd go for a GW Tanned Flesh or Terracotta basecoat, wet- and then dry-brushed with something like Elf Flesh, Bleached Bone, Vomit Brown, Dwarf Flesh .... possibilities are endless, really. You'd be amazed at how fussy clients can be about representing a *particular* brick colour

If you want to really go to town on brick, start with a Tallarn Flesh + Bleached Bone undercoat - to represent the mortar courses - then overbrush your base "red" onto the individual bricks to leave mortar showing through. Work your way up through highlights to taste, and glaze the mortar with very thin black+brown ink in patches.
For ultra-anorak brickwork, take a look at something like
this brick selector from one of the suppliers we use. You can start getting into variegated bricks, random splotches of colour, engineering brick DPCs, whatever....
