rgbEx255 expression but in JavaScript

Hi,

I cannot find how to generate a colorValue type number from Red, Green and Blue channels anywhere. I don't know how to use system expressions from even sheets, there is nothing on that in the documentation.

Can anyone help?

Also is there somewhere a definition what datatype colorValue in construct3 use anyway? It would be even better.

ps.: Scripting reference is frustrating to use, there is no search only for javascript functions and while wasting 3 hours on this quest to convert some numbers I found a lot of developer posts that we shouldn't be using undocumented functions and people are still using them. How can I know if the function is documented or not if I cannot browse reference other than page by page?

The scripting APIs usually use an array of [r, g, b] for colors, with each component in the range 0-1. What do you need a color value in scripting for? Generally color values are specific to the event system.
