Representation: RGB

• Instead of using 24 bits per pixel, one can have 16 bpp by simply using 5 bits for each of the primary colors, and one bit for transparency.
• Higher color image rendition would result, however, if the 16 bits were allocated more in accord with the Human Visual System, such as might occur with YUV coding where the color components are subsampled, typically 4:2:2 (or 4:1:1 with DVI).
• Transparency allows see-thru to the background, for example, as opposed to an opaque image.
