## Usage

This node converts between different color representations, it can convert between the following systems.

 - RGB - Red, Green, Blue
 - HSL - Hue, Saturation, Level
 - HSV - Hue, Saturation, Value (brightnes)
 - CSS - CSS color names

### Inputs

For the first 3 input modes the node will attempt to determine the input format of msg.payload from the 3 following:

 - a string with defined separator.
 - a 3 segment array with values between 0-255 for RGB.
 - a 3 segment array for HSL and HSV with Hue is between 0-360 and Saturation, Level, values 0-100.
 - a object with keys red,green,blue with values between 0-255.
 - a object with keys hue,saturation,lightness or value,brightness with values between 0-360 for hue and 0-100 for the others.

For the CSS input mode the msg.payload should be a string containing the name of a CSS color.

### Outputs

Output type can be configured to be either a 3 element array, an object or a string. The 3 element array will contian the 
aproprate values in the same order as expected. Objects will have matching keys and the string will be the values from the 
array joined with a separator.

If the CSS output mode is selected then the output type will be forced to be a string.
