This particular problem, which is not to be confused with similar-looking problems with `.im8` images in later versions, was a known issue with Motif:

 1255448: cde on Solaris x86 has yellow tinting problem with TrueColor default visual

An X server that allows changing the class of the default visual should be able to work around this.

Xorg and Xming document an option for that:

`-cc int default color visual class`

However passing `-cc` with `PseudoColor` or its constant from `X.h` (`3`) has no effect on the default visual reported by `xdpyinfo`.

Alternately the issue can be fixed by installing the appropriate Motif patch for the Solaris release (e.g. 2.5 → 103947, 2.5.1 → 104195).
