RBG Color numbers for the brightest light?

I have an LED light with Tasmota installed. I have the RGB set to 255,255,255 which is a dull white. In playing around with the color settings in Tasmota I am able to get the light brighter by moving the sliders left and right and just playing around with it. I cant though translate that playing around into a set of numbers that I can use to input into the yaml. Can someone tell me what RBG numbers they use to get the brightest lights?

brightness: 255

Hi, you can use the developer tools: Developer Tools -> States.

Enter the entity-id and you can see all attributes of the light, including RGB values, when it is turned on.

Thank you very much!
