New Flag in Button Command

[Anonymous]

Hi, i can see a new flag with button command -hlc -highLightColor which requires float values as the -bgc flag

window -width 400;
     columnLayout -adjustableColumn true;
     $btn1 = `button -label "button 1" `;
     $btn2 = `button -label "button 2" -enable true`;
     button -e -hlc 1.0 1.0 1.0 $btn1;
showWindow;

-highlightColor(-hlc)	float float float
The highlight color of the control. The arguments correspond to the red, green, and blue color components. Each component ranges in value from 0.0 to 1.0.

Trying to use it but simply nothing happens. Can somebody guide me to the solution. 

Thanks
