change background color of widget in order to chroma key GUI in video
I've used a Cyton brainwave kit for a few years and have recently shot some video documenting a performance. I'm wondering if it's possible to change the background color of an OpenBCI GUI widget, for instance the Time Series widget, so that it can be chroma-keyed over a video sequence. Any advice on this would be greatly appreciated, thanks!

Elgordo, hi.
The GUI source code is here:
https://github.com/OpenBCI/OpenBCI_GUI [top level folder]
https://github.com/OpenBCI/OpenBCI_GUI/tree/master/OpenBCI_GUI [source code files]
https://github.com/OpenBCI/OpenBCI_GUI/blob/master/OpenBCI_GUI/W_TimeSeries.pde [Time series widget]
This page shows how to build the GUI from source using Processing language:

Hi William, thanks, I do not write code myself but I'll see if I can get a friend to help me with that, thanks!

Thanks for the link, this looks pretty straightforward, I'll be back in a few days when I get this organized and will post a response appropriately. Much appreciated!
GitHub allows you to search for names of 'variables' used in the source code. For example:
https://github.com/OpenBCI/OpenBCI_GUI/search?p=1&q=backgroundColor
But if we instead search for only 'background', many many matches occur. This is because 'background' is referenced many times in the 'library' functions that Processing graphics uses. Most likely these hits are NOT what you need to change.

Thanks again for your help, I won't have time to look at this until later this week but your advice is very helpful.
