#172 Filter Colour In Capture

[Joscpe]

It would be nice to have colour filters available in the whitelist and blacklist options, or else a separate colour filter all together; perhaps it could handle an array of colours even.

One aspect of this, is to avoid corrupted output when coloured elements surround the text. Or else maybe I only want (to keep or avoid) certain words which are a specific colour in the sample.
I've attached an example where in Visual Studio, the red squiggle underline interferes with the capture. Note, in Word the squiggle is more distant and this doesn't happen.

Another use would be, if I wanted to capture a link which has different font colour in the screenshot.
