A basic stain stains the bacteria (the stain is a positively charged molecule that attaches to cells which are negatively charged or to negatively charged molecules in cells.) A negative stain does not stain cells (why its called a negative stain), it stains the background around the cells.
Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives. The procedure is based on the ability of microorganisms to retain color of the stains used during the gram stain reaction. Gram-negative bacteria are decolorized by the alcohol, losing the color of the primary stain, purple. Gram-positive bacteria are not decolorized by alcohol and will remain as purple.
