I try to test what vale a color variable has with

if (myColor==Color.green)

and even when I know it is true it doesn't work, any idea how I could
solve this?

Presuming myColour is of type Color, you should be using

if ( myColor.equals( Color.green ) )

UNLESS you are absolutely sure myColor was initialised with

myColor = Color.green;

rather than say:

myColor = new Color( 0x00ff00 );

You get into similar problems with equals vs == with Strings.
