Add ability to change active field color

[OlivierCOUPAT]

In creo 2.0 the color of the active field (dark pink)  is too close from the color of a non-active field (pink), So it is not easy to make quickly a diffrence between these 2 fileds. In Creo Element Pro 5, it was easier

                                            

     CREO 2.0                                                                                                       CREO ELEMENT PRO 5

It would be great to be able to change the default color of an active field
