Blue light

Hi, all!

I'm new to Hexen Mode of Doom maps.
Now I want to make a box (sector), let's say it's an aquarium. You can't enter this sector, but you can see it from outside. How can I give this sector (and everything that's in it) a blue color when it's seen from outside?
Maybe someone can give me the keyword, or the lindef action, which I can lookup at the Wiki?

Thanks,

Milian

Solved!

no. 190 is what I was looking for.

If you ask something like that, you shoukd tell us that you are working with ZDoom and that with the wiki you also mean the ZDoom.org WIKI
