I tried to add an image for laser tech to the Ufopaedia. However, it seems that openXcom makes some kind of color transformation on the images.
I saved the image as 24 bit .png and 8 bit .gif, but both show different colors in the game compared to an image viewer (the 8 bit .gif is really ugly
). For saving the images I used gimp and paint.net.
Is there somewhere a guide on how to prepare images for openXcom, so that the correct colors are shown ingame?
Ruleset and images I used are attached.
