As far as I know, there aren't any records of Duchy of Warsaw Poles using captured Russian ordnance between 1807 and 1814. The Kingdom of Poland later used exclusively Russian guns, but that was between 1815 and 1830 and well after the end of the Napoleonic wars.
The Poles did not have a cannon foundry of their own and apparently had to rely on the Kingdom of Saxony to cast their ordnance. As a result, they mostly used captured Prussian guns and also Austrian ones after the 1809 campaign, during which the Polish army captured 62 guns from the Imperial forces. The Prussian 6 pdrs were eventually re-bored to take French ammmunition and the French also supplied Gribeauval guns in limited quantities to their Polish allies.
Most illustrators show Polish gun carriages painted in the same olive green colour used by the French artillery, though the captured Prussian ordnance issued in 1807 may well have remained in its original medium blue shade for some time : there is no consensus over the matter. Ditto for the Austrian guns captured in 1809 : it's not clear whether they were left in their original colour or repainted once pressed into Polish service.
