IIRC GIF's are limited to a specific pallete on .NET. There are workarounds, but they were above my understanding.

GIF files are limited to 256 colors as far as I know, so it resorts to dithering. PNG is probably the format you need.
Or you can look here for a solution using a complex quantizer to build a custom palette (I don't take responsibility for the code in the link, never tried myself).
This other link from Microsoft has an in-depth analysis of the problem.
Hope this helps.

See my update to the original question. This answer eventually pointed me to the solution.
