texture not followning from blender

I collored this cube in blender with random collors in texture paint and saved it in my assets folder. I then imported it into unity and draget the matereal onto it. I still have no collors, and when i dobble click the materal (and open it in blender) what i painted is gone and im only left with the background collor.

What am I doing wrong?

You have to save the texture you created in blender171858-texture.png

Then Import into unity and drag the texture onto the model
