The Omnitrix center is not a natural green. It is a sci-fi interface color, sitting inside dark casing and associated with the hourglass symbol and alien silhouettes.
Because the device is worn on the wrist, the green has to read quickly. Low saturation makes it look like a normal watch light instead of Ben 10 tech.
Push saturation and brightness high, then check the hue. The green should feel clean, not forest, military, or teal.
If you need one rule, treat the dark watch body as contrast. The core can be intense because the surrounding shape keeps it under control.
