12 bit color palete & RGB 3-3-2

I would like to make web page for P800 and other 12 bit devices. How can I simulate 12 bit mode in Photoshop or wher can I find 4096 color palete?

And how can I set up custom RGB 3-3-2 GIF color palete?

thx, realTime

You cannot simluate 12-bit in Photoshop. No file formats support 12-bit (to the best of my knowledge). I suggest you build your website in full colours and let the P800 do the translation, it shouldn't be too much of a colour deficit with 4096 colours anyway.

I'm working on this:
-first I made image of 16 colors that simulate 4-bit grayscale ant save the custom palette

-then open any 24-bit image and split channels

-save 3 channels as GIF vith custom palete (16 colors of 4-bit)

-reopen it, and merge channels

as a result a got 12-bit image

but it does not louk the same as it does on P800 device  
Devices like the P800 or the SPV show colours quite differently than on your computer screen due to the nature of their screen sizes and light conditions etc. I personally wouldn't go thru the trouble of making a 12-bit image because it would as you mentioned be so off anyway.


ps. what format are you saving your 12-bit images in?
