Describe the feature you'd like to have added

It is very nice that we can color laser nodes but always needing to set Red, Green and Blue individually is quite cumbersome. I have a few colors in my mind as a hex value e.g. #23c2ba which for some reason is a lot easier to remember for me than R35 G194 B186.
So I would highly appreciate it if you could also add a text field which accepts a hex value for the color.
Bonus points if I can also set the Alpha with it (8 digits instead of 6 where the last 2 are the alpha aka RGBA) e.g. #23c2ba66 for 40% alpha
