How Can I Add Color Texture To A .fbx File

Hi, when i import a fbx file in buildbox, the colors are gone, what can i do for having them ?

 

from fbx editor page or any key frame animation
choose fbx you want to edit and under texture you will find color

 

I am sorry but this is not very clear, where is supposed to be this fbx editor page ? i mean we can add import the color or texture from the sprite editor in the sub scene manager, but i don't have them

 

click on this small pin

 

okay this sends me into the sub scene manager like said but i don't see how i can put the colors back ... sorry but what am i supposed to do ..

many colors need texture
this is image from sub scene manager

 

me i don't have those texture, what can i do ?
