Hello,
I am asking about the way to implement the 256 colour palette for openttd as I am facing a nightmare to implement it in GIMP.
Any reply would be highly appreciated from any new GRF developer.
I would give credits to all who will help me in this in the future IRTrains set.

There's nothing you need to set up in GIMP if you want to use 32bpp color palette. It uses the entire RGB range from 000,000,000 to 255,255,255. All you need to do is specify that you're using 32bpp in your code.

Sir, I mean to make 8bpp.

You still need correctly paletted 8 bit sprites if you want to use company colours or other remapping effects in 32bpp.

I still use a 20-year-old version of Paint Shop Pro to make OpenTTD sprites. It's very hard to find a modern graphics editor which has decent tools for manipulating and applying 8 bit palettes.

You can import this palette in to gimp. I don't remember if it's the DOS or Windows version of the palette, though.

EDIT: vv better link below

My apologies, I misread your comment.

Here's a link with GIMP profiles for both Windows and DOS palettes (I suggest using DOS), and profiles for GIMP, PaintShopPro and Photoshop.

You also can use a GRFMaker sprite editor, which has the integrated TTD palette, DOS/Windows-compatibility and some good tools.

Thank you, legendary NewGRF developer and Mr. Kamnet, legendary moderator for your insight!
