Teletext time travel

I still use teletext daily as an app on my phone. One of the fastest way to check sport results and read some news.

What that meant was that, whenever you wanted to change color (text and/or background), you _had_ to insert a space in the page.

So, for example, showing text on a background Dutch or German flag was easy, doing so on a Belgian, French or Italian one could not be done nicely.
