RGB/Color Picker Helper

I feel like it would be really helpful to have an RGB helper… right now I use a text input helper to specify a color I might want RGB lights to be in the future, based on an automation or script. However, in the helper I specify the RGB color as [255,123,55]… which has no easy visual indicator as to which color that is. Having a color picker helper where it can inject that string into a helper variable I think would be great.
Thanks!
