Gram stain is a differential stain that differentiates bacteria into two groups - Gram +ve and Gram -ve. The basis of this differentiation lies in the composition (lipid contents) and thickness of cell wall of these bacteria. Bacteria are called Gram +ve, if they retain the crystal violet colour even after alcohol washing. Whereas, cell wall of Gram -ve bacteria is thin, rich in lipids and decolourise the crystal violet colour of Gram stain.
