Air carrier Captain reported the dark lighting conditions; wet surface; and dull paint markings at ORD made following the taxiway centerline difficult.

Narrative

During a purposely slow taxi out at 3 to 5 kt. ground speed on a poorly lit; dark; and wet taxiway; the amount of turn required for the next taxiway became uncertain so the FO (First Officer); pilot monitoring; quickly applied the brakes and said; Stop." That was an appropriate and timely intervention to avoid further deviation off centerline. After a few seconds of verification; we turned further right to keep on assigned centerline in a sharp turn and proceeded without further incident.Contributing factors include: dark/low ambient illumination night; wet ramp and taxiways with pockets of standing water that obscured the taxiway centerline marked with rather dull paint; the required sharp turn was on the FO's side of the jet; Ground Control had just urged the crew to get moving while it was taking a momentary pause to verify unfamiliar taxi instructions and routing - BS; A; U; G; hold short of TT for Runway 27L - and; if memory serves correctly; only the left side of Taxiway A had dim blue taxiway side lights illuminated - which created confusion.Much later during cruise; the Purser advised that the stop was felt as more sudden by the passengers and cause a several drinks to tumble forward off individual passenger drink trays and that a few passengers in First Class cried out."
