We need lots of different colors for category and we can switch colors on text. If we write Resistance the text automatic switch to blue only for Resistance in the text.
Please don't. Colors don't bring any value within posts that can't be achieved with bold or italics as well. Instead they are usually abused (think of glaring red) or hard to read.
@TimWolla Niantic can use it to bescribe on commuity what it is. On Reddit we easy see the post it is about update and update have easy new color. More faster and easy to see if everything not are black.
