As has been said, the French infantry, both Line and Light had basically standard colourings for all regiments (apart from a brief period around 1807 when some regiments were issued with white uniforms and coloured facings). HOWEVER, the fine details of cuff design did often change from regiment to regiment, as did the colourings of elite company distinctions (epaulettes, plumes, cords and sword-knots), while drummers' and sappers' livery could vary wildly from regiment to regiment.
A lot of these simply aren't known, but the Osprey Men-At-Arms books on Line and Light Infantry do have fairly comprehensive lists of the known variations.
