Early PC video cards had a composite video output, and clever programmers have learned to control the artifacts to produce more colors than intended. 8088 MPH by Hornet, CRTC, and DESiRE gets 1024 colors out of a 1981 IBM Color Graphics Adapter… that the 16-color CGA standard was named after. 😂
PAL consoles can often output RGB just because SCART existed, with NTSC versions of the same consoles only having S-video as the best connection without modification.
Edit: S-video has fewer artifacts than composite, but that ruins some effects like turning the “transparency” of water in Sonic the Hedgehog into a checkerboard. The checkerboard was always there, but the blurring of composite made it appear to just be darker shades of the colors behind it (dithering). The illusion of more colors was important for Sega’s 512-color Mega Drive when Nintendo’s SNES had a full 16-bit palette of over 32,000 colors and “real transparency” (selectively replacing pixels with a lighter/darker shade).
