I will mine my pictures from other posts to make this post.
Some Tilean 'bravi', figures mostly from Wargames Foundry's 'Casting Room Miniatures' range. They're painted in all sorts of colours to give a militia impression:
From the same range as above, these are militia pikemen, carrying a Morrite emblem of my own design, amalgamating the common symbols of the raven and the hourglass.
More casting room miniatures next, being some mounted nobility
Here are the two chancellors of the mercenary company the Compagnia del Sole, liveried as the rest of the company, and with the Myrmidian banner emblem behind - half a sun and a white baton. This is my own amalgamation of suggested Myrmidian emblems.
The Compagnia's mounted men at arms are Perry plastics:
The Compagnia's heavy foot regiments are Perry's and old GW and some other ranges too ...
Another (much, much smaller) mercenary company, with their own livery, is Pandolfo's galloper guns:
And some northern mercenaries of the VMC (a Marienburg Trading Company) in Tilea:
They have their own Myrmidian banner:
I provide the figures for the player of Duke Guidobaldo of Pavona. They have a blue and white livery:
Here are mercenary pikemen, liveried (partially) in the orange and blue of Remas. The figures are an old range whose name eludes me just now:
You can see some more Reman liveried guards behind the Morrite priests here:
And here are several artillery pieces in Reman livery:
My religious cultists have a livery also, based on the Morrite priests' grey and dark-red (with some purple thrown in for good measure):
Even the halflings in the army of Verezzo are liveried:
And here is the muted livery of the Bretonnian mercenaries known as the 'Brabanzon':
Here is a banner based on the historical banner of the Sforza family (of interest to you, GP?)
And another banner of historical Italian origin:
Here are some Reman Church of Morr banners which are versions of historical papal banners (the first being a musician & standard bearer in one!). Crossed keys were common:
And some cross-keyed overkill:
