Watch face on Vivioactive 4s - Digital Hour color

I have a vivioactive 4S and have selected a custom watch face through IQ.  I changed to a digital clock, and have changed the color of the minutes, but can't seem to change the color of the hour.  How do I do that.  when I select the paint can and select a color, it only changes the minutes... I can't toggle to the hour.  Help!
