I suggest also using this website to make sure the colors met accessibility check. I make sure that the colors have enough contrasts so people can differentiate them. https://webaim.org/resources/contrastchecker/
Chris, This is one of the most useful blog posts from any source that I’ve received. Rather than just referring us to Canva, you walk through all the steps. I love the idea of creating the powerpoint blocks with color labels. And super thanks for the site to check colors for persons with color blindness, which if I remember correctly affects 11% of people–8% of men and 3% of women.
Your post is great!
Lyn
