Quick small incremental update this time!

First

The script sniffs the output being generated. When a color is detected, a square with the detected color is shown next to the color `#` value to give a visualization of how the color looks like.

Then

The follow feature got a sizeable performance boost. I had made a stupid mistake that was causing too much work being done repetitively making it slow (ups?). I found it and fixed it.

Have fun!
