Why is there no colour on my OBJ files in my project?,How do I add an OBJ file with colour to my project?

I just imported an OBJ file of a 3D satellite image. I am wonder why there is no colour on the OBJ in unity while there was in Blender when I exported it. Any ideas on how to fix this? Export as a different file type? I have attached 2 images in this question. One of in Blender and one of what happened when I put it into Unity. ![alt text][1] ![alt text][2] [1]: https://i.imgur.com/lSxtIBR.png [2]: https://i.imgur.com/XQU8nCQ.png
