Displaced Gamers recently posted an excellent video that explains chroma – Or, essentially how colors are created with analog video signals.
The video starts out by breaking down analog video formats and demonstrating how the signals are generated. I love the examples they used of oscilloscope captures shown over 100% color bars! This is one of the best visual examples I’ve seen that demonstrates both how colors are produced and what the technical differences are between RGB and YPbPr ‘component’ video.
I’d recommend this video for anyone who’s a bit more curious than the average gamer as to how these analog signals we use work and it’s also a great video to watch if you’d ever like to get into signal testing on an oscilloscope. In fact, I’d recommend watching this before watching the videos Ste and I did.
