I’ve noticed that the color of the chart “Shed humidity” (yellow / rgb(242, 204, 12) in my case) is different from one displayed in the legend (red / rgb(242, 73, 92)) when the dashboard is initially loaded. When I click on the legend (hide/show particular sequence), the legend is refreshed and yellow color is correctly shown everywhere:
The chart is a standard “Time series” visualization with MySQL datasource.
