Every LED device shares the same theme list, so a wheel, a button box and a flag box can all wear the same look.

Built in themes: DNR, Racing, Red Fade, Blue Fade, Green Fade, Yellow Fade, Orange Fade, Purple Fade, Pink Fade, White Fade, Arctic, Sunset, Rainbow, Citrus, Tokyo and Gulf Oil. Button boxes also carry a Precision Sim Engineering theme, and flag box gear numbers add a Lovely Dashboard theme.

Custom is the seventeenth option and the only one that unlocks per button, per rotary and per LED colours. If you want to colour individual inputs yourself, this is the theme you need.

Each device has three theme slots, on their own tabs:

• Idle Theme, shown when SimHub is running but no game is active
• Game Theme, shown once a game session has launched
• Button Effects, where the per input colours live

The Custom Theme Helper builds a theme for you: pick one, two or three colours and it generates a full custom palette from them. You can also set the idle theme to Static or Breathing, and apply a Dim Effect so idle lighting is not as bright as racing lighting.
