Texture color is not right after import

Hi there, I ve created a texture for a road in bodypaint. This is the screensnap in bodypaint

Then, after import the model to unity, the texture is not the same as in bodypaint This is the screensnap in unity

The importer setting for this texture is as below turn on mipmap filtermode Bilinear aniso level 2 format RGBA compressed DXT5

Anyone here can give me a hint what caused this problem? Very urgent, guys
