Would someone be willing to make this plug-in for me? 15-bit color

5 bits per channel (+ alpha bit)

Make an image with the colours you use, export, re-open, create palette from image.

Palettes seem to be limited to 10K colors (15-bit would be 32K). Not very manageable anyway. But yes for the auto-conversion.

I was not thinking of anything like full  HiColor-32K number of colours.

How many colours does a pixel artist use? I do not know but probably favourites & not that many.

Most of the stock palettes are around the 256 mark and less, The largest I have and very occasionally use is the pantone palette with around 1000 colours.

Out of interest, converted that to 15 bit and sorted. Wonderful format .gpl, opens up in a spreadsheet FWIW attached.

Quote:That one would be easy. It would just be a script that rounds the current fg/bg colors to the nearest 5-bit equivalent (actually drops the 3 LSB's).

There you go, get stuck in. 
Seriously, it surprising that there is not a plugin to reduce the number of colours in this way. There is posterize but not applicable. Not much in the way of other applications either. I thought ImageJ might do it, but no. Vague memory that PSPro might (or might not). Is PS the only one?
