Can I change the onboard RGB lighting of my Razer keyboard?

I recently bought the Razer Cynosa Chroma keyboard and play it on my Ps4. I have set up and programmed it on my laptop, but this keyboard can only change the colors on the laptop via the program when I press the selected fast function (say: fn + f1) to change the color. (When I lock it from the laptop and connect to the Ps4 only the preinstalled color fade option appears.) So I wonder if I can reprogram it via a program so that it lights up in the desired color (somewhere the pre-installed Color fade Option would be saved.) Would be good if someone could help me

This works only if the keyboard has on-board memory for profiles, but unfortunately does not. Is not possible in this respect.

And then what is the color fade effect stored

Sure, it is stored on the keyboard, but you have, so I want to guess now without research vague, no access to it.

Hmm okay, i know it's just a color and i can't make a big deal out of it, but is there maybe a usb plug with an onboard memory that will change color as soon as i connect the keyboard?

Unfortunately, this does not work, the lighting is controlled by Razer's own tool, or generally a software that runs on only one operating system. And the keyboard can't be persuaded by itself to use something else.
