Many thanks!  Sorry I'm weak with music - both demos missed it. plus4emu can work with these inverted colors - it is very good for 5 years old emulator. However it is a bit wrong with 40x36c - it shows inverted colors instead of standard ones. Is it the first emulation bug for this very exact program? I've discovered (but not proved for all tv and monitors) that it is impossible to have all screen inverted - my tv inverts colors twice in this case. So we need all knowledge about PAL in order to use all ability of our plus/4.
BTW Vice also doesn't support PAL colors properly. 
It is interesting - are there similar demos for Commodore 64, Atari, Spectrum, Amiga, ...?
@MIK I wrote an utility for you to test all 233 possible colors. It is at the end of page at http://litwr2.atspace.eu/plus4.html  IMHO it is possible to distinguish every color by proper monitor tuning.
@Degauss See http://www.videointerchange.com/pal_secam_conversions.htm
The keyword is "color stability". Engineers lovingly defined NTSC as actually meaning "Never The Same Color". :-)
@Gaia It is an interesting idea about affecting color burst. I want to try it! However I don't understand the matter about the breaking of "TED's colour carrier signal".
