processingjs red() green() blue()

Question

I want to send a sting from processing js to javascript with the color to use in css. so formatted like: "rgb(255, 0, 0)" (or whatever color values).

no matter what i try i get this error:

Uncaught TypeError: number is not a function

I did several tests and it is always red(.... that is causing the error (and probably green and blue).

String getRowColor(int r) {
  if (r > rows || r < 0) {
    return null;
  } 
  else {
    color c= colors[r];
    String cStr = "rgb(";
    cStr += red(c)+", ";
    cStr += green(c)+", ";
    cStr += blue(c)+")";
    return cStr;
  }
}

You question says "Javascript", but you've tagged this "Java". Which is it? — Oliver Charlesworth, Jan 03 '12 at 17:28
I am not very familiar with processing.js but can you try `cStr = join(cStr,str(red(c)),", ");` — Howard, Jan 03 '12 at 17:33
oops it's javascript. Most of the times i use java, my mistake. For the rest both processingjs as processing have functions red(c) etc. — clankill3r, Jan 03 '12 at 19:22
I figured, but i don't think it's a dumb enough question to warrant -2 and no solution :) — Timothy Groote, Oct 27 '14 at 09:26

I think that: color c= colors[r]; should be: color c= color(r);

The rest of the code implies that `colors` is an array of `Color` – Timothy Groote Oct 21 '14 at 13:31
