This mod adds keyboard lighting functionality to Kerbal Space Program. Talking about it really doesn't do it much good. Take a look at this awesome video from GameInstructor, who tested the mod and explains it very comprehensively: 




  • Function keys 1 to 0 are only lit, if the underlying action group actually does anything. The keys are displayed in two different colors, depending on whether the action group is toggled or not.
  • The keys for SAS, RCS, Gears, Lights and the Brakes are lit up in different colors, indicating if the respective system was activated or not.
  • The amount of resources in the current stage is displayed on your keypad and the keys to the left of it (PrtScr, ScrLk, ..., PageDown)
  • The color of W, A, S, D, E and Q varies slightly depending on whether you're in precision or normal steering mode
  • The keys for timewarp control are lit either red for physics timewarp or green for normal timewarp

Full list of game effects

  • Stylized Kerbal Space Program logo that fades in on every scene that does not contain any noteworthy keyboard interaction (pressing Escape to go to the menu not being noteworthy enough to light up the key)
  • In the vessel editor, different kinds of keysets are lit up according to the current editor mode.
  • Control keys and toggleable function keys are lit up in different colors, showing whether the function is switched on or off during flight.
  • Reduced keyset lit for EVA mode
  • Resource gauges displayed on the keypad and the keys above the UpDownLeftRight keys.
  • Power failure animation on vessels that need power to be controllable
  • Crash animation that triggers when crashing a vessel's root part
  • Splashdown animation that triggers, when landing on water.
  • Vessel electricity status displayed on any Razer mouse and mousepad connected
  • Vessel heat displayed in three colors (blue = cool, red = warm/hot, yellow = you're in trouble), uses the scrollwheel and logo on mice and the bottom LEDs on the mousepad, as well as the keyboard logo.
  • "Dear GF, please don't disturb me now" feature on the headset. The device is colored red, when you can't quicksave right now. Turns green once quicksave is allowed again.
  • Vessel height above ground displayed on F1 to F4 keys (F1 = 10m, F2 = 50m, F3 = 100m, F4 = 1000m). The intensity changes, e.g. if F1 is fully lit and F2 is half lit, you are 30 meters above ground.


  1. Unzip the release archive and place the 000/KSPChromaControl folder in your KSP GameData directory.
  2. Start KSP and witness the awesomeness of highlighted function keys while kerbaling through space
  3. (optional) Move the file ChromaAppInfo.xml from the mod folder into the KSP folder, to allow Synapse to recognize the game properly.

I installed this with no luck, Razer Synapses doesnt want to work for me. are there any good troubleshooting steps i can follow? 

Did you download from CurseForge or GitHub? Only the CurseForge version has the required DLL's included.

ETA: @zer0Kerbal, your mod works great! It really adds to the experience. The additional effects are nicely done.

Thank you @Jack Wolfe! All the credit goes to the original author - @FauserneEist

Although I did add one or two, and fixed one or two (like the / and \ being swapped)

+1 :rep:for the assist!

Glad it is working for you @xD-FireStriker!


I had it working - then it stopped on my system - which is a mess - constantly installed, and uninstalling - moving things, my system would give LTT a headache! :o

Think you can update CKAN for this?  I just got my keyboard fixed, would like to install it with CKAN if possible



It is up for an update in January, I will publish the SpaceDock listing and push the CKAN button .

I am about to replace the lmb in my two razer mice - and so would like it to work with those and my Huntsman as well.

What was wrong with the keyboard if you don't mind answering?

One of the keys wasn't working, I really don't care that much about the colors, it's nice, but the feel of the keyboard is why I like it

I downloaded the last version from January, and am getting these errors constantly repeated in the log:

No idea what's going on, let me know if you want the complete  log file


Edit:  I think I figured it out, had to have the Chroma Connect module installed in Synapse.  You may want to update the instructions

What's really odd is that I have to install the module in Synapse 3, but need Synapse 2 to control the keyboard. although I don't need Synapse 2 to be running for KerbalChroma to control the keyboard lights

You may want to put a try/catch around the  ApplyToKeyboard() to report an error and exit if a failure condition is experienced, otherewise it can be a frustrating experience for anyone trying to use it
