Chromatin is an organized structure of DNA and proteins which is found in the nucleus of the eukaryotic cells. Differences between euchromatin and heterochromatin (they both are the parts of chromatin) are as follows:

Euchromatin	Heterochromatin
The light staining portion of chromatin is known as euchromatin.	The dark staining portion of the chromatin is known as heterochromatin.
