For the love of the Traveller... ARMOR SHADERS SHOULD BE CUSTOMIZABLE!!!
I believe some type of custom armor shader kiosk would net some silver purchases from players. Honestly, I'd pay $20.00 to have a custom black armor shader with lime green accents/details.
You could show a preview in the kiosk where the armor colors change in real time as you pick it out, that way you know what you're getting. Make it cost so much silver for how many colors you add or seperate it to each section of the body even. There's a lot to work with there.
I know this probably has a snowball's chance of surviving Oryx's gaze, but I really feel like it's a decent malleable idea.
There is already a shader like that for getting all the oryx armor set. EDIT (hard mode armor set)
Get all 4 pieces and you get a black shader with neon accents.
Go look under your shader collection kiosk
