Privacy boxes on video - color to number chart needed

[AlpineWatch]

I have an inexpensive Ebay 720p camera that Ive been using as a weathercam however before I share it with the world I'd like to block the imaging of a neighbor's driveway.

From the 'video shade' tab, I have 4 windows I can turn on and size. The color choice is 6 digits and is currently 000000.
I set it to 088888 and a box was now blue.

Is there a chart somewhere showing colors to digits? I'd like to just use a gray color.

This is one of the tools I use when I want to visually pick a hex color:
