Yeah that's it, red and green are swapped, blue is the same.
A photo from a TV screen showing a version of blargg's full palette demo hacked for PAL:
pal-nes-emphasis.png
(From top to bottom 000, 001, 010, 011, 100, 101, 110, 111)
Which version of the palette test ROM is that? Because I've got 2 versions which have different layouts and different emphasis orders:
1. "version 2", where each color section is upside-down ($30/$20/$10/$00 top-to-bottom) and emphasis is ordered White,Blue,Magenta,Red,Yellow,Green,Cyan,Black (000,100,101,001,011,010,110,111)
2. "optimized version", where each color section is right-side-up ($00/$10/$20/$30 top-to-bottom) and emphasis is ordered White,Red,Green,Yellow,Blue,Magenta,Cyan,Black (000,001,010,011,100,101,110,111)
Your image seems to be using color layout #1 but emphasis layout #2, which is a bit confusing.
