I am thinking of buying this keyboard https://www.kogan.com/au/buy/kogan-full-rgb-mechanical-keyboard-blue-switch/
However I have some concerns. The product mentions compatible OS:
I am concerned that I would not be able to control the keyboard without using its propriatery software/driver found on Windows.
Is it possible to still control the RGB lightings on this keyboard, even if I had to make the software myself?
Does it require binary blobs or something?
Hi
I do not know about your keyboard! However I use Corsair keyboards,
there is a program for them Off the top off my head I cant remember the name.

Not familiar with that keyboard, but there is always openrgb to investigate - it is created for the purpose of accessing rgb controls without Windows being needed. You setup may be one of the possibles…
I am lucky enough to have Corsair mouse/keyboard so I can use openrgb OR ckb-next to control them both…
Would this work even if I used linux-libre kernal?
Not enough knowledge (of what the linux-libre version contains, mainly) to say - but FWIW don’t expect it to care about kernel version. It looks a bit tricky to set up though - so don’t give up TOO easily 
Best hope is someone else has tried it successfully and posted how they did it…
I am just worried cause since linux-libre strips all binary blobs so I mean it could be a concern.
Cool mate thanks mate =D
Here is most popular project for that RGB stuff, doesn’t seem it has your keyboard 
Maybe you can write them and ask for support, or try to code it yourself 
As long as it doesn’t require binary blobs?
I don’t know doesn’t look like it, do your research in their repo 
From a quick look at Kogan keyboards and pricing, I wonder if they are ‘rebranded’ Chinese keyboards such as Reddragon &c. If so, you may be in luck…
I actually just heard that they amazon was also selling the same keyboard but it was rebranded so not sure what the original keyboard brand is, I hope it is reddragon 
Does this support mouses as well?
Yep, from the looks of it it support a range of devices even some RAM
Interesitng mate thanks mate
there is also piper for the mouse that will change dpi, lighting, and button mapping if you have something like a logitech g series or something like that that would have software on windows to change these things.
If you are still thinking of buying this keyboard, maybe you should think about buying a keyboard that is supported by the above apps?

I have a cooler master set MS121 RGB keyboard and mouse. It has it’s own firmware on the mechanical keyboard. Lighting is controlled by F keys. I have no additional software. I wouldn’t be surprised if that one works similar.
