yes, that’s right… you are going to need a span element to contain the word with a different color.
PG will insert a span for you from the text editing mode (double click inside a text block to select the mode, and a blue menu will appear, highlight the word and click span
to exit text mode, click done.
from there you can either create an inline style on the span to choose the color (quick and dirty, not recommended) or add a class to the span that you can use to assign a color in your .css file
