`set_color` needs a terminal, because its output depends on your terminal characteristics! I suspect that you have a call to `set_color` in your `.config/fish/config.fish`, possibly in a command substitution or a function call, and this gets run for all new instances. I suggest you use `if status --is-interactive` in your config.fish to only set colors and other similar variables if you are in an interactive session. This will have the added benefit of improving (very slightly :-) startup time.
