A really important thing to remember!

Keep in mind that every object, frame, and text character can have both a Fill color and a Stroke color.

The color gets applied according to 1) what is selected on the page, and 2) whether the Container formatting or the Text formatting box is selected, and 3) whether the tiny Fill box or Stroke box is selected.

You’ll probably forget often to check all three things. Well, maybe you won’t forget, but I’ve been working with a page layout application for more than twenty years now and have selected colors at least five billion times, and I still forget to check each box before I apply color. Aaarrghh.

Here are the several places where you can choose whether to apply the color to a Container or to Text and whether you want it to apply to the Fill or the Stroke (border). Use the tool that feels more convenient for you.
