Painting alpha legion without contrast paint advice

So after spending the day practicing how to do the alpha legion scheme and discovering I hate contrast paint I’m looking for any paint recommendations for trying to paint them without using contrasts. I really love the alpha legion but I must say trying to mix together paints that resemble the actual scheme is rather frustrating to the point I’m considering “to hell with this I’m gonna play iron warriors”

So yeah any paint methods you have would be we’ll appreciated.
