CGA Graphics - Not as bad as you thought!
About this video
The 8-Bit Guy covers IBM's 1981 CGA graphics system, including how composite output and artifacting produced extra colors beyond the nominal palette. He argues CGA looked better in period than it does on RGB monitors.
Why it appears in the archive
HN recommends it for showing how old developers exploited the smeary nature of composite signals and what CGA really looked like on period hardware.

If you want to see how this type of colour magic works in video form, the 8-bit guy does a GREAT video on this: [VIDEO] He shows all the interesting artifacting that makes these extra colours possible.
Read original comment ↗That's a thing more relevant on PC: this video has some more information on the phenomenon (I think) you're talking about: [VIDEO]
Read original comment ↗CGA colors were designed for display on composite; the issue is most people were using digital cables, which had the garish colors. [VIDEO] has a great overview of what was possible.
Read original comment ↗The 8-Bit guy did a great piece on CGA that goes into detail about how old developers abused the fuzzy smeary nature of composite signals to output somewhat decent graphics. The tricks however didn't work when people upgraded to proper monitors and as a result a lot of CGA games look much worse today than they did on the intended equipment of the day. [VIDEO]
Read original comment ↗Bare in mind the displays of the time would have blended the pixels. Likewise those who complain that CGA is “only 4 awful colours” have clearly never used a proper CGA system the way it was originally intended. The following YouTube video does a good job describing what CGA was really like back in the day: [VIDEO]
Read original comment ↗Your comment got me thinking: "Wouldn't be nice if existed an 'awesome list' for this kind of content?" After a brief google search the best I could find is this [0] and it seems to be abandoned. Does anyone know a better source for this type of content? I'm leaving some random links to great channels that produce this kind of content: - CGA Graphics - Not as bad as you thought!

Read original comment ↗[VIDEO] You can make funny tricks when passing image as composite. Where with those you can produce other colours. And state of computers were quite limited and primitive then. On other hand for business use, those are still acceptable, everything was text anyway.
Read original comment ↗One thing about CGA is that it was meant to be output via composite video instead of VGA-style RGBI. This video demonstrates the difference: [VIDEO]
