King Henriques would be wearing a short sleeved chain mail hauberk (shirt) that just passes his knees, and Iron spangenhelm (also called a nasal helmet or norman helmet), drawstring pants, a cloak, a short tunic (to his knees), and an akheton (padded tunic). Hes holding a kite shield (judging by the height) and sword. The color of the clothing would be anything you want it to be, as there was no specific color code for military uniforms at this time. Obiously his armour (helmet, chain mail, etc) would be metal colored. For pics go to this site: http://angevin.org/
The uniform, clothing, armour and weapons throughout 11th-12th cent. Europe was basically the same, so this site will give you an accurate perspective. Sorry I had'nt responded to this before, I just found your question.
