Hello,
I have been trying to get Razer Chroma to function properly and am at my wits end. So far...
- Full uninstall / reinstall of ES2 (including all local files and anything I can find in the registry)
- Full uninstall / re-install of Synapse 2/3
- Confirmed that EndlessSpace2.exe is actively taking control of the lightning of my Razer devices (as indicated inside the Synapse application)
- Confirmed that the option is toggle in the UI section of the settings.
- Disabled all mods and confirmed ES2 is latest version

Any other thoughts or hints? Chroma works very well for other games (Mechwarrior 5, Divine Divinity Original Sin 2, etc)
