When I read about American World War One soldiers in the Osprey books, they mentioned how American soldiers would wear red armbands when carrying messages so they wouldn't be harassed by officers or military police. Of course, the red armbands made them a prime target for the enemy too. But when reading about soldiers from other armies, none of them mentioned such insignia for couriers. So what did they do?
Now, as for making them more of a target, probably not. The main hazzard would be having to be out of the trenches, as I'd assume that the poor bugger with the message, would either be being sent from the attacking force, to or from the nearest working telephone or from the nearest working telephone to the attacking force!

Hi
The distinguishing marks for specialists were laid down in BEF documents, SS 135 'Instructions for the Training of Divisions for Offensive Action', of December 1916, Section XXXII, has the following: Scouts - Green Band. Runner - Red Band. Regimental and Company Signaller - Blue. Carrying Party - Yellow. Mopping Up troops - White. Salvage Parties - Khaki Band with 'Salvage' in Red letters.
These bands were made 'locally' and were meant to be 1 1/2 inches wide and worn on the left forearm.
Also troops carrying wire cutters or wire breakers were to wear a piece of white tape looped through the right shoulder strap.
I should mention that arm bands were worn for other purposes in an attack but on the right arm. An example from the 11th Australian Infantry Brigade from an order dated 16 July, 1917, has the following:
Distinguishing band will be worn on right arm 4 inches below Battalion colour patch.
Assaulting troops - Yellow.
Parties to establish Red Posts - Red.
Parties to consolidate Red Dotted Line - White.
A lot of distinguishing bands were used for different purpose, so best to look at photos carefully and try to relate them to associated documentation if possible.
