Components color issue

I was starting to build my house on SketchUp, I put components doors and windows with my favorite colors then I saved my project, closed the software and I went to bed. Suddenly I don’t know what happened, when I open back my project to finish my work, some of my components was white colored and even stacy the architect has lost her body color and painted in white, please tell me how to fix it.

check if your ‘View’ is set to ‘Shaded With Textures’…
