The '''IBM 5153''' (~~officially~~ the '''IBM Personal Computer Color Display''') is the 13-inch RGBI colour monitor IBM introduced in March 1983 to pair with the [[IBM Color Graphics Adapter|Color Graphics Adapter (CGA)]] in the [[IBM PC (5150)]] and [[IBM PC XT (5160)]]. It ~~produces a 640 × 200 monochrome or 320 × 200 four-colour image at 60 Hz and~~ can render all 16 CGA colours, including the famous '''brown''' that lower-quality third-party CGA monitors typically reproduced as dark yellow.

The 5153 reduces the green signal amplitude ~~by about one-third~~ internally; this is the trick that produces "brown" from the (R + G) bit combination at low intensity. Third-party clones that drove R, G and B with equal gains showed dark yellow in that combination instead.
