A DESCRIPTION OF THE REQUEST :
The Color-class already has a method, which converts a string of the type #RRGGBB into a RGB-Color-Value and creates a new java.awt.Color instanse from them.

I think it would be usefull to many developers to have a method doing the opposite thing. It could be called for examplte 'toHexString()' or 'encode()' (as a counterpart to the existing 'decode()'-method, that i mentioned above).

JUSTIFICATION :
It think such method would be used very often and therefore should be a part of the class


---------- BEGIN SOURCE ----------
Just a possible implementation, which i am currently using:

  public String toHexString() {
    StringBuilder sb = new StringBuilder(7);
    String r = Integer.toHexString(getRed());
    String g = Integer.toHexString(getGreen());
    String b = Integer.toHexString(getBlue());
    sb.append("#");
    if (r.length() == 1)
      sb.append('0');
    sb.append(r);
    if (g.length() == 1)
      sb.append('0');
    sb.append(g);
    if (b.length() == 1)
      sb.append('0');
    sb.append(b);
    return sb.toString();
  }
