Genesis lighting and shadow effects and higher color counts - Emulation shots

Early European Genesis print ads listed the Genesis' color capabilities as much higher than the system's 64 color limit. This ad has since been used as an example of Sega false advertising, in the style of Nintendo or Sony, about their console's capabilities. The ROM Demo below demonstrates the Genesis displaying 1536 colors at once in a non-game environment, using the Genesis' hardware lighting/shadow effect. This same effect was used in actual software to increase the apparent color count on screen, or in Sonic 2's case, actually break the 64 color limit.

In actuality, the Genesis' color limitation was 16 colors per sprite or background tile, with 4 palettes available at once for on screen colors. Since a palette could be changed in between the NTSC format's interlaced displays, the Genesis could cheat this limitation technically. By and large most Genesis games stayed below 54 colors on screen, while some used dithering and other artistic approaches along with the blurring produced by the video output to create an image that does effectively have more than 64 colors in it.
