I tried to upload two screenshots (but I can’t see them…). The first is a flypaper texture uploaded by me. The texture is outlined in blue middle right. It is pinkish. It is yellow when I use it.
The second screenshot is of one of your textures. It’s outlined in blue 2nd from the top, grayish with brown blotches, looking exactly the same in the preview as in the main screen. No hint of yellow.
My monitor is calibrated, but when you can see the two on the same screen, that really doesn’t matter. My textures are set to be stored on a different drive than my boot drive because I have a SSD drive but I can’t see how that would matter. If I load the texture as an image, it displays perfectly.
