How do I make colored sectors in Boom?

[Robot J]

Title. I want to make a room that where you'd flip a switch and the room would go red. I know it's possible but I don't know how to do it. How do I achieve it

Simply, you can't.

Only way to make colored sectors is using zdoom base ports, and i thing above 2.2 or so.
Not sure.
But thats not a feature present on boom format at all.

There are really strange ways to make colored sectors on vanilla-boom but that imply that you mess the colorpal and with just one color, and its not recomended as it mess the colours of the game if made wrong.

@boris thanksfully corrected me, so his post is the one to read.

Sorry for the trouble. :(

This is not correct, you can do it with the Boom linedef action 242, see https://soulsphere.org/projects/boomref/#ld242

 

There are some limitations, though, most noticeable is that the colormap is only applied when you are inside the tagged sector. A way to fake the coloring while you're outside the sector is to apply a texture of the color you want to the outside linedefs and give it the action 260 to make them translucent.
