I doubt the problem is that their color, but rather that the producer software is creating bad TIFF files. It is possible to build libTIFF with so-called "Old style JPEG" (OJPEG) support, but it looks like it hasn't been in this case. That file doesn't open in GMail's preview or OS X Preview app, so Tesseract isn't the only piece of software that's unhappy with the illegal TIFF. You might able to use ImageMagick or some other utility to convert them to an acceptedable format.
