import processing.core.*;

import wordcram.*;

public class Myprocess extends PApplet {

public void setup() {

color c = color(255, 204, 0); // there is an error.

...

}

So we can see the code above, there is always the error showing that the color can't be resolved...I imported the newest processing.jar...I don't know why....Any clue?

You should read the http://processing.org/learning/eclipse/ tutorial...

Another important note. The Processing "color" primitive does not exist in Java. In fact, in Processing a "color" is really just an integer (32 bits with red, green, blue, and alpha components). [etc.]

EDIT: Beaten...

I'm guessing that you are working from Eclipse. In this case, you encounter the fact that Processing stores color variables as ints. In fact, the pre-compiler will simply convert color to int. Processing provides utility functions for converting to the color format (such as color()). All you need to do is change your colors to ints.
