Review comment:
       I don't enjoy suggesting a code repetition, but isn't the following an 
improvement over letting python users have to make their own colors:
   ```
   class Nvtx:
       # Palette of colors
       RED = 0xFF0000
       GREEN = 0x00FF00
       BLUE = 0x0000FF
       YELLOW = 0xB58900
       ORANGE = 0xCB4B16
       RED = 0xDC322F
       MAGENTA = 0xD33682
       VIOLET = 0x6C71C4
       BLUE1 = 0x268BD2
       CYAN = 0x2AA198
       GREEN = 0x859900
   
   def nvtx_range_push(name, color=Nvtx.ORANGE):
   ```
