"Seaweed mode" (Dark mode)

Dark mode is a must to have on any website in 2020. In keeping with the theme this should be implemented, however it could be a very dark green colour with a subtle pattern of sushi seaweed. This will be easy on the eyes and also pleasing to the meme gods. Icons to be able to switch from "tuna/salmon" and "seaweed" also should be considered in the design (instead of the traditional "sun" and "moon" icons).
