Red Filter for Nauticam RX100V Housing

I have a Nauticam RX100v housing with flip adapter with wet wide angle. I wanted to add a red filter to pair with video lights with ambient light filters. Was wondering if there is anything that would fit between the wide wet lens and the port or should I put a red filter inside the housing?

These might work:
