Three old palette sets renamed and three new ones added. Every group has a core palette plus 6 variations - 7 palettes total for a region within each group.

A color chart for each palette was going to be included, but the smallest most practical size (x2 resolution) would have driven the size of each set from ~14KB to well over 500KB.  For bandwidth and download considerations they are being left out.  However, feel free to download the Color Demo ROM here:  (  Color Selector Demo (2003) (PD).zip   1.42K   6 downloads

It works fine for both PAL and NTSC, and the color charts will display.

Absolutely, there is no definitive or final palette - but 42 different ones are provided here for each region, a total of 84 palettes!  You're bound to find a close to if not perfect one for you and your setup.

Enjoy!

Background Details:
---------- -------
If interested in "why" this update, in part it is due to the error I mentioned earlier with starting with a PAL base and trying to create NTSC palettes from it.  I ensured the front end (technically accurate 'raw' values) were set to the respective region after figuring out my error, but forgot to fix the back end (conversion to CRT).

It resulted in an overall redder palette for FINAL (Which was renamed to the CRTTVR), that is within the reasonable tolerance shift, and of course allowed for yet another CRT palette to be a 'truer' less red/more green palette (CRTTVG).  The former less red more green palette, ALT_FINAL is actually the neutral and renamed accordingly (CRTTV).

The other two new palettes incorporate work in previous threads in harmony with a request fulfillment (WARM_LCD) as well as my own personal drive to achieve the color shift palette that has been documented and captured (WARM_CRT).
