The New LineColor Output Attribute

As I update my indicators to use the new API I notice that the new line color attribute does not acccept the enumerations from the color class.if i use the following:

[Output("SMA", LineColor = Color.Red)]

I get the following Error:

Error CS0030: Cannot convert type 'cAlgo.API.Color' to 'string'

I wants me to use a hexadecimal string to assign the color, like "#FFFF0000"  But is a pain to remember. Is there another way to assign the colors without having to memorize the hexadecimal codes?
