Razer Blackwidow Chroma v2 changes color when I go into a game (Fortnite)?

I got the Razer Blackwidow Chroma v2 (keyboard) and the Razer Naga Trinity (mouse) I got my color combi I wanted, but when I go to Fortnite, the color changes to completely white… How can I adjust that it stays even when I go into games like Fortnite etc… (Pictures below)

There's a setting in Synapse where you can switch off. Synapse has quasi preconfigured settings for certain games (such as key-highlighting). Would look in the program itself.

Check your Fortnight "Extra Game Options" Settings for "Peripheral Lighting. It is likely set to "ON", which gives Fortnite control of device lighting. Set it to "OFF" to let your settings prevail.
