I think there is a bug in my MATLAB R2019a. When I wanna change the color of a figure plot line, or colorscale, or similar. I click the respective menu icon and then the color selection box opens. I can click a color and press OK, everything is fine.
However, while the first color change always works, sometimes when I try that again at some later point (regardless of trying to change the same color again or the color of any other item) the color selection box just stays blank/empty. See the attaches screen snippets.
That is very annoying as I cannot change colors anymore once that happened. If it happened once it stays like this until I restart Matlab.
Any suggestions?

When you are trying to change the color of a figure plot line for the second time delete the marker which has been created earlier and add a new color marker or use edit marker color option
You may refer to the steps mentioned in the documentation:

I think you have misunderstood the problem. I'm having the same bug on two different machines, both running 2019a.
