Many meshes with different color performance
I want to create an application that allows user to load an image and makes 3d visualization of this image. The final effect will be like this: 
Currently I create a cube for each pixel in the image. Each mesh has it's own material, cause they have different colors. This causes very low performance. Is there a way to optimise it? Draw calls depends on the image loaded, in this case it's about 16k.

16,000 draw calls is crazy! Assign vertex colours to the vertices of each cube and then use a single material with a vertex-colour shader instead = 1 Draw Call.
