I tried setting mission objectives (during the game via a trigger) to this block of text but everything from the second line down remains gray.

<13><04>The Industrial World
<13><05>1783-1945
<13>Created by rayNimagi
<13><04>America
<07>Event: Manifest Destiny
<05>(Sends an army to conquer the West Coast.)

What I'm aiming for is this:

Event: Manifest Destiny
(Sends an army to conquer the West Coast.)

In-game, the alignment works fine. It's the color (which should change on the fourth line ("America")) to white, then green on the next, and back to gray. It all fits in the mission objectives window. What am I doing wrong?

The gray colour tag makes everything after it gray, regardless of what other tags you put after it. Use a different colour, or use gray for the last words only.

That's strange, I can use gray in other texts and it works fine. I'll just change it for the objectives then. Thanks!

If it's on a single line, then gray overwrites everything. It's likely that mission objectives considers it all one line. Ah well, it's one color. Whoop-dee-doo.

Invisible got the same effect. I forgot if there were any other colors like that though.

There is not. Grey and invisible are the only ones.

do you guys know why it goes over everything after?

Use <1E> instead.

Because that is how SC uses it. It is used in like disabled buttons and such, which must be completely greyed out.
