How can I set symbol color by diferent value?

[Aaronsi]

my code is:
var simpleJson = {
"type": "simple",
"label": "",
"description": "",
"symbol": {
"color": [210,105,30,191],
"size": 10,
"angle": 0,
"xoffset": 0,
"yoffset": 0,
"type": "esriSLS" // esriSMS, esriSLS
}
"visualVariables": [{
"type": "color",
"field": "status",
"stops": [
{ "value": 1, "color": [52,176,0,191]},
{ "value": 2, "color":[254,203,0,191]},
{ "value": 3, "color":[223,1,0,191]}
]
}]
};
geoJsonLayer.renderer = new SimpleRenderer(simpleJson);

The problem is that it doesn't work. Can you give me some suggestion?
