If you know the history. never the same color isn't true at all, and pal had the same issues till 1970 in many respects. My overly simplistic response does not include all dates and changes but gives the general idea. Somewhere on the forums I and others completely dissected this to it's inception. so search it out for some good ole technical talk and fun. You can drill down on phases and quadrature encoding if you so desire... I'll make mistakes now as it's all fading away, but it doesn't mean it isn't in there. It's easy enough to rediscover.
Like I said, they adjusted the color pot and made a tweak here or there. but for the most part if the teleivision is adjusted to broadcast standards and the computer is adjusted to the tv it all comes out pretty much like it should. Artifacting is where the real evil begins. And it was fun getting all the artifacts included in a handy dandy video upgrade everyone loves. that discussion took a year or more til someone could see it and verified it.
Anyway my days of calibrating displays are long gone, well almost, this past week..
frequency- notice 59 and not 60? because 59.99 whatever is just like the Atari STILL. I listen to folks complain about real time clocks over the years.. once the Atari is counting the time you have to adjust for the real frequency or you need to pull the time from the real time clock and update it before it drifts. The Atari is not at fault. it's timing is correct, the error is with the persons code. This is true to this day. Please note how bad an iPhone camera mangles this display!
The slightly less than 60 is significant for programming also, you have to cut a things just short of what you think you have so that you don't end up getting some issues. How many times people miss count...
