The uniform of the Grenadiers of the Imperial Guard was very similar to that of the Grenadier of the line : Both were made of a blue coat, red piped white cuffs, white piped red lapels, blue piped red cuff flaps, red epaulettes and brass buttons. The most notable difference was the headgear : Grenadiers of the Guard wore a tall bearskin cap with a brass plate stamped with the Imperial eagle, with white cords and red plume, and a red patch with a golden grenade on the top of the bearskin. Other differences include the blue collar of the Guard Grenadiers (instead of red pipped white collar for Line grenadiers) and longer red turnbacks with gold grenades (instead of white turnbacks piped red with red grenades).

Napoleon usually wore the non-Hussar/old styple uniform of a colonel of this regiment on Sundays.
The uniform was that of the Grenadiers of the Old Guard, differences being a plate less bearskin, a red-over-green plume. The epaulettes had green pads with red fringes. The embroideries on the turn-backs were a combination of a bugle and a grenade to signify Chasseurs of the Old Guard. The cuffs were of light infantry design.
The uniform of the Fusiliers-Chasseurs was that of the Chasseurs à pied of the Old Guard. The only change was the headgear, black shako with the imperial eagle, white cords and brass chin straps. With tricolor cockade atop and red-over-green plume.
Raised from sailors of the French navy who had distinguished themselves, the battalion of Marins wore a distinctive, elaborate uniform resembling that of the hussars. Their officers bore titles of rank derived from their seagoing compatriots, and the overall commander of the marines bore the rank of capitaine de vaisseau. Their duties including manning boats and other watercraft used by the Emperor. The Marines of the Imperial Guard wore blue vest and trousers piped aurore (orange-gold). They had aurore hussar-style braids on their tunic, gold epaulettes and red cuffs. Their shako was black piped aurore with a red plume.
The Dragoon Guards wore green coats with white lapels and red turnbacks. They also wore aurore (light orange) aiguillettes and epaulettes. They wore brass helmets with a long black mane, a simulated leopard fur turban and a red plume (white plume for the highest officers). They rode chestnut horses.

The trumpeters wore a light blue tunic with white lappels and crimson turnbacks and collar. The mane on their helmets was white and the plume was light blue. They wore grey horses. They also had a white uniform for parade, consisting of a white coat with light blue lappels and collar lined with gold.
The uniform of the Horse chasseurs of the Guards was very similar to the hussar uniform, comprising pelisse and Busby, but the unvariating color of the dolman and breeches was green with a collar piped of gold. Their pelisses and cuffs were red pipped with gold. The plume of their busby was red-over-green.

It was the Chasseurs that usually provided personal escort to Napoleon, and he habitually wore the non-Hussar uniform of a colonel of their regiment in recognition of this service.

Here is the color scheme of their coats:
