EGA's native graphics modes are planar, as opposed to the interlaced CGA and Hercules modes. Video memory is divided into four pages (except 640×350×2, which has two pages), one for each component of the RGBI color space, with each bit representing one pixel. If a bit in the red page is enabled, but none of the equivalent bits in the other pages are, a red pixel will appear in that location on-screen. If all the other bits for that particular pixel were also enabled, it would become white, and so forth.
