Hello!
I would like to change the color of the milestones in a gantt chart.

The code I have is as follows:

%%{
init: {
'theme': 'base',
'themeVariables': {
'primaryColor': '#fde116',
'primaryTextColor': '#f',
'primaryBorderColor': '#fde116',
'lineColor': '#F8B229',
'secondaryColor': '#f89c84',
'secondaryBorderColor': '#f89c84',
'tertiaryColor': '#fff'
}
}
}%%
