Colors from palette turning invisible

[Zeta Reticulan]

Hello,
I'm trying to use the shades of orange and red from this palette that I got directly from UFOpedia, but it keeps turning invisible when I convert the pgn to 8bit using this site: https://buscher.eu.pythonanywhere.com/spritepalette What's going on?

That file is not entirely reliable, the RGB values are slightly offset from the palette used in most of the community tools.
You can simply use the actual palette in the file you get back from the spritepalette tool.

Alternatively, I've attached a BMP file that contains the UFO Battlescape palette. Try using that one. The image is actually only a single transparent pixel, just use the palette information.

I found a working one. Thanks.

I'll attach these palette charts to this thread, perhaps they can be useful.

Both are for the Battlescape palette.
