As I said before All FCU/MCP actions and movement of any control lever like flaps, gear, parking brake or anything else like the condition levers are not to be done from muscle memory or subconsciously. These are identify and do actions and as long as that's not done no ergonomics or colour schemes will work. More the experience or familiarity with the cockpit more you are likely to fall prey to it. Gear is shaped with wheel, flap looks like a wing they are not close by move differently but people have retracted wrong control. Keep those hands in the lap till something is ordered then think before you reach for it. There's simply no other way.
