The times they are a changin' and I think it may be about time I changed my craftworld color scheme a bit to go with them. I originally made the color scheme for my world around 12 years ago and since then some of my taste in color has shifted a bit.

This was the first thing I ever painted for my craftworld, my first test model. I am not very good at painting and I don't have a steady hand so I wanted colors that look good at a distance among a crowd of similarly painted models. The contrast in bleached bone and hawk turquoise fit the bill and hit my two favorite colors to boot.
But since then, I have grown fond of the contrast between blue and orange. So tonight I have played around with orange to see if it could be worked into my color scheme.

This was my first attempt... i immediately hated it and stopped. Edging is difficult for me and it did not seem to fit well, but maybe someone here has an idea that would make this work?

Take two: an orange wash over the bleached bone base. Not bad... but I think he looks a little like a walking cheeto... In addition I have a lot of already completely painted units and implementing this on them might be difficult.

My last test and honestly my favorite. Rather than make orange a primary color alongside the blue, it replaces white as my secondary (and white becomes a tertiary with red). This also has the benefit of being the easiest to implement on my already painted units. The downside would be that it might look like my units are using nerf guns...

here they all are together
To make this an effective test I may need to try one of these out on something bigger like a wraith lord or wave serpent, but I wanted to get some opinions/advise first. Do you all like one in particular or have some ideas of ways I could update my color scheme?
