Вы всегда можете просто указать цвет узлов при их инициализации:
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
style: [{
selector: "node",
css: {
"shape": "roundrectangle",
"height": "40px",
"background-color": function(node) {
if (node.data("colored"))
return "#FBFBFB";
else
return "#58D68D";
},
"label": "data(id)",
"text-valign": "center",
"border-width": "2",
"border-color": "black"
}
},
{
selector: ':parent',
css: {
"background-opacity": "0.333",
"text-halign": "center",
"text-valign": "top"
}
},
{
selector: "edge",
css: {

"curve-style": "bezier",
"target-arrow-shape": "data(arrow)"
}
}
],
elements: {

}

}
},

},
{

},

}
}));
