Idk what props it all has, but you can always target it with css.
.ia_symbolComponent--stopped.ia_vesselSymbolComponent > .vessel_cylindricalTank_tank_conical {
fill: red
}
.ia_symbolComponent--running.ia_vesselSymbolComponent > .vessel_cylindricalTank_tank_conical {
fill: green
}
–default and --faulted work too, faulted already has a fill animation on the tank tho so might want to use somethign else there
(i tried some of the props to color, but i only seemed to color the water, idk if i missed one tho)
