Hello again, trying to convert RGB to HSV found two nodes which I can't get to one. One is called 'Color Converter' which is suppose to take any color input and return the values of all others. When I try that it gives me the same output as I gave input with no errors. The second one is called 'Color-Convert'. You specify an input type and the output type you want. When using input as RGB and requesting out og HSV it want's the input as an array. Using a debug module I verified my input was an array howerver it gives me an error saying it's not. Any help would be appreciated.

Here is an example with it:

```auto
[{"id":"61d7519e0b341ef0","type":"debug","z":"03ac9f8a4a6deca0","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":570,"y":40,"wires":[]},{"id":"85d28496a14d1f0d","type":"inject","z":"03ac9f8a4a6deca0","name":"","props":[{"p":"payload"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payloadType":"str","x":110,"y":40,"wires":[["c27a5a0b1b42dbf0"]]},{"id":"c27a5a0b1b42dbf0","type":"change","z":"03ac9f8a4a6deca0","name":"","rules":[{"t":"set","p":"payload","pt":"msg","to":"{\"r\": 0, \"g\": 255, \"b\": 0}","tot":"json"}],"action":"","property":"","from":"","to":"","reg":false,"x":260,"y":40,"wires":[["0b21b8d3f22ab435","e10d42f1e1a3c39c"]]},{"id":"0b21b8d3f22ab435","type":"debug","z":"03ac9f8a4a6deca0","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":390,"y":120,"wires":[]},{"id":"e10d42f1e1a3c39c","type":"chroma","z":"03ac9f8a4a6deca0","name":"","outFormat":"hsv","array2object":true,"floatOutput":true,"inputRelativeValues":"percent","outputRelativeValues":"percent","x":440,"y":40,"wires":[["61d7519e0b341ef0"]]}]

```

Its the same as yours but using msg.payload as the variable
