Are you using the binaries from the Release page?
The package we are providing does not provide color support for CAD format.
You can see it with the (no metadata) in the information:
OpenCASCADE module: 7.6.0 (no metadata)
If you want full support, you will have to build your own f3d with an OpenCASCADE library supporting TKXDESTEP and TKXDEIGES modules.
For reference, here is the script we are using to generate the OpenCASCADE library for the f3d package. We are not including TKXDESTEP and TKXDEIGES modules because it requires additional dependencies if I remember correctly.

Yes I am using the binaries from the release page.
I have compiled/installed OpenCascade 1.6.0 with the additional toolkits:
BUILD_ADDITIONAL_TOOLKITS TKSTEP;TKIGES;TKMesh
Then compiled f3d enabling the OCCT and assimp (installed from the repositories) modules:

If you tried to build the master, the --version option is not working well, try to checkout v1.2.1 instead.
Still, even if the --version is not displaying OCCT support, f3d should be able to open STP and IGS files.
I am able to load the STEP file but still no colors (latest master)

Can you attach the step file here? It seems I cannot export the file without OnShape account
Sorry it took time but I had a quick look. It seems the file do not contain any color information on the curves nor the surfaces. I don't know if the issue is coming from the OpenCASCADE reader we are using or the OnShape STEP exporter.
The model contains colors and OpenCascade is capable or reading them because CAD Assistant loads and displays colors fine:
Hi @VictorLamoine
I tested again with a colored step saved from freecad and cannot find any issue:
It may be an opencascade issue or our own issue but without identifying what makes your file special, it's hard to move forward.
@VictorLamoine do you have other examples of files that fails the same way ?
I have created an other example but can't reproduce the issue with this new project: https://cad.onshape.com/documents/40aed6aac6d07380ae0eccef/w/f9de146d81b7733ba00e0d2a/e/77afd1673e070bbd56300323?renderMode=0&uiState=65ae4da2b657bd694137a618
The file from the first post still doesn't display colors, I have tried re-exporting from OnShape and the problems still remains.
Short answer: no I don't have an other file to reproduce the problem at the moment.
@snoyer do you know if Mayo rely on OCCT ?
I don't know the exact details but it does
