I've finally burned an Eprom in order to run Eckhard test programs.
The description of PAL colours that Eckhard sent some time ago seems quite
accurate - perhaps 'gold' is more 'brown-gold' than 'gold' - but I think
that finding accurate descriptions isn't so important.
Instead, in order to write a multi-standard game, here are some things that
I must understand:

- Is the number of hues the same in PAL and NTSC, or does one of the two TV
standards have more colours?

- How can colors be mapped between the two systems, I mean can I write a
table made of lines like: NTSC X (green) = PAL Y (the same green), or at
least: NTSC X (green) = PAL Z (the PAL green nearest to NTSC green)?
