can the representation learning parts from the colorization model be trained independently?

See in the classification or segmentation task, the final test model is just the parts before the layer "conv8", and the structure is also a little different from the original parts in colorization model. Since these parts can be trained directly from imagent or pascal dataset for classification or segmentation, it is a little confusion to say that the colorization model holds the cross-channel encoding ability.
