title: Why are all of my text mesh pro (tmp) the same color on my Unity canvas
body: <p>I have been working on a project in Unity. It's a 3D project and I have a 2D canvas. I have been going through and making several buttons with Text Mess Pro (TMP) on them. I have been changing the color of the text by adjusting the Color Gradient in the Inspector. But when I tried to changed one of them the other day, it got stuck on Black. I don't remember what I did to cause this and I didn't realize it at the time, but it also changed the text on all of my buttons to black.</p>
  <p>As I've been looking for a solution (and through previous experimentation of my own) I have learned that changing the color gradient can affect other TMP's that share that gradient, but I can't figure out how to get any of the text colors to change now.</p>
  <p>Does anyone have any suggestions?</p>
  <p>(My project is in Unity 2019.2.6f1)</p>
