Bug 493262

Thank you for the bug report!

Seems that being unable to disable this in the Brightness applet is the more central issue, as that is very user-facing. This applet also has a bugzilla component, so I'm assigning this there (although background service should also not become reenabled on its own).

The switch in the applet is meant to make this possible.

So you're saying you set the switch in the applet to off and it the keyboard backlight is reset to white once, but at the next reboot it has the accent color again?

Does your ~/.config/kdeglobals have an entry "DeviceLedsAccentColored" set to false?

Is this post addressed to me?

Yes.

Ok.
Where can I find this setting? 
"~/.config/kdeglobals have an entry "DeviceLedsAccentColored"
I tried looking on the system drive, but I couldn't find it.
I'm not that advanced in Linux.

Thanks, this is the right file and it doesn't have that entry. So it seems that for some reason the choice to disable the feature is not saved in the config file as it should, so it's not remembered across reboots.

Ok. So we have to wait patiently for a fix. :)

Until the new version with the bugfix is released, you can manually set

DeviceLedsAccentColored=false

as a new entry under the heading

I added this entry, but the service is still running after restart

Is only the service running in the background or does it also still enforce accent color?

You mean the accent color service? I have it disabled

It is not clear to me what you mean by "disabled the service". You disabled the kameleon entry in Background Services in System Settings, or you diabled the feature by setting the switch in the applet to off?
But forget about the service for now. When you set the switch in the applet to off and reboot, is the switch back on, and is accent color enforced again?

Sorry, but I don't know anything about the applet.
Where can I find it?

I don't use applets

Brightness and Color applet

This is where you are meant to disable the feature.   
That the background service is still running is expected, because we still need to check whether to even show the control depending on whether the feature is at all supported on your device to, and to react if you change your preference about turning at on.
So don't think about disabling the background service in system settings. Just check that after changing the configuration manually, the switch is off as it should, and accent color is no longer enforced.

This feature has always been disabled

UPDATE.

I set Brightness and Color to off as you mentioned earlier and the Chameleon service no longer starts by itself after a restart.
Your advice was right, Thanks :)
