as above, this:
```
src.visible_message("\blue [src] starts filling its tank from [target].")
```
should be something like this:
```
src.visible_message("<span class='notice'>[src] starts filling \his tank from [target].</span>")
```
```\his``` is a byond macro, it automatically expands to the proper gender (male, female, plural, neuter) based on the gender of the last ref (```[src]``` in this case)
