RGB color change

Hello!
does anyone know how to make a RGB work with 1 single color but different intensities or patterns? I am trying to make an effect of continuous intensity increase, but i cannot find any XOD box that allows me to do it.
Thank you very much in advance!

What kind of RGB? There are several neopixel libraries (Libraries — XOD).

The simple single RGB, the white one with 4 pins.

is there any possibility?
Thank you so much for your answer.

I think the ‘fade’ node is what you are looking for.

thank you so much!! it worked
