Haven't had any updates for awhile due to hitting a roadblock on the blue swatch for this kit. I really struggled with this one...
There weren't many clear screenshots of this kit in natural lighting in the previous season of TCW, until season 7 came out...that was when I was able to determine with fair certainty that not just one kind of blue swatch was just used throughout in this kit.
The airborne trooper showed up several times in season 7, with more clear and natural lighting, and I was able to make out three subtle but distinctive different blues used in different parts of this kit: on the helmet, the torso including the cod, and the shins.
Staring at the screenshots for hours and researching the variety of different shades of paints and brands out in the market, I came up with my own forumlations and will reveal them as I go through the painting process. I've also studied Kade's and Eqdizzle's thread and their choice and usage of their blues (definitely valid in their own right), compared the character concept designs to the final screens used in the episodes, and came up with a medium that I'm fairly content with, visually to the naked eye and to various camera photo exposures.
Here are the sample swatches taken in various lighting conditions.

---Shin Armor Painting and WeatheringOne of the fine details to note when painting the stripes for the shin armor are the top corners of the side panels that are close to the upper three darts. The left and right inner shin panels have sharp angled corners, while the outer left and right shin panels have the corners round. Here are my reference shots coming from the charater concept designs and screens from S5 & S7...




These are the paints I'll be using: Rustoleum Aged Gray, Montana Gold paints; Stealth-G7070, Signal Blue-G5075, Ultramarine-G5080




Previously I primed the shins with light gray primer...so then I went ahead and masked and painted the shin darts with the Montana Gold Stealth-G7070, but use of any dark gray will do.

Next I wanted a more warmer gray, so I used the Rustoleum Aged Gray to paint the main body of the shins.

Masked the side panels, so I can proceed to paint the middle stripe with Signal Blue-G5075 and dusted with Ultramarine-G5080

I then masked the middle stripes and painted the side panel stripes, measuring out the top and bottom stripes at 1/4"in and 1/8"in for the left and right stripes.

Next, I sanded down the side stripes for weathering.

In addition, referencing from the screenshots, on the side panel stripes, there is a Blue-green color corrosion or rust on the beskar. This is most likely resulting from contact with water, oxygen and carbon dioxide over time, causing a coating to build on the surface with makes the metal more resistant to further corrosion.
So with blue and yellow acrylic paint to get a greenish mixture, I did a wash to the striped areas. Then I did an overall black wash to everything.

I highlighted the darts by dry brushing a little light gray to it. The black wash, after drying, looked OK to the naked eye, but didn't standout much with the camera...

...so I applied black graphite to simulate and accentuate more carbon scoring.





All set for now...
