Color in Mesh Tool turns gray

[GRAPHICPROF]

I am creating an illustration using the Mesh Tool. When I select the color I want for 1 or more points the color turns to gray. Can someone advise why this is and how to correct it? Thanks for your time.

After posting this, I found my own answer from a Youtube video. Go to the color panel. It was indicating grayscale. I changed to RGB.
