According to SPR files | Creatures Wiki | Fandom powered by Wikia[^] the colour values are palette indexes:
Quote:
The actual image data is simply color indexes arranged into horizontal scanlines. The mappings between color indices and 256 RGB colors is given in the PALETTE.DTA[^] file; Multiply the red, green and blue results returned by 4 to gain the full colour range.
If you don't have the palette file you can try to use the default palette provided in the link.

So you have to load the SPR file into memory, create a bitmap of the same size, and set the bitmap pixels to the RGB values retrieved from the colour table using the colour index from the SPR pixels.
