Hello, I try to retrieve information during step import (name, color,..). Starting from IESample, I have found a way to analyse the AIS_InteractiveContext after importation (list of shape with relations) but I did not find the way for retrieving name and color information.

you can try like this :  

   Handle(TDocStd_Document) aDoc;
    Handle(XCAFApp_Application) anApp = XCAFApp_Application::GetApplication();
    anApp->NewDocument("MDTV-XCAF", aDoc);
    STEPCAFControl_Reader aStepReader;
    aStepReader.SetColorMode(true);
    aStepReader.SetNameMode(true);
    aStepReader.SetLayerMode(true);
    aStepReader.ReadFile(theStepName);
    aStepReader.Transfer(aDoc);
    TDF_Label aRootLabel = aDoc->Main();
    aShapeTool = XCAFDoc_DocumentTool::ShapeTool(aRootLabel);
    aColorTool = XCAFDoc_DocumentTool::ColorTool(aRootLabel);
    
    /*TDF_LabelSequence colors,shapes,layers;
    aColorTool->GetColors(colors);
    aShapeTool->GetShapes(shapes);
   

you will get colors infomation, but cannot know which face the color on. I am trying hard to get the color on the relative surface.
