If you're stuck in one lighting mode (rainbow, stalker, or static), you need to find where the LED NEXT button is.
Pressing the LED NEXT button cycles through the LED color options.
On the factory default layer, which is the layer that the Raise comes with before you configure anything, the LED NEXT function is located on the Dygma key on the right half of the Raise.
If pressing this key doesn't change your lighting mode, it may be that you're now on a different layer, or that you changed the function of this key using Bazecor.
To put the LED NEXT function on your Raise again, go to Bazecor > Layout Editor > select a key > Media & LED > Next light effect.
Apply changes and SAVE (on the top right corner).
Then pressing that key several times will change your LED lighting mode.
It can also happen that after pressing LED NEXT you pressed a move to layer key and changed to Layer 1. This means you need to go back to Layer 0 to be able to cycle through the LED colors again.
