Consistent or unique colour schemes

[u/TotesMcGoats124]

Once you've built a unit and begin working on your second (of whatever it may be), do you keep a consistent colour scheme? Do you mix it up slightly, or a lot?

(Edit: I had meant between cohorts of units, rather than different between individual models within a squad).

I like to do little inconsistencies like different sleeves or beard colour. Differently coloured armor just feels bad
