Turning On lights from Node - red - Color picker helper

Hello,
I am using node red for all my automation. The only thing that I regret is the lack of a developing user interface that let me choose color, hue, brightness from a front end picker instead that only finding the correct RGB values for the script section (like I do when setting up automations with HA front end).

is there any helper I can install to have a color picker in a call server (turn light on) node?

Thank you
C.
