<p>Thank you for the intersting input! The teaching in question was from the USA so NTSC for sure. <br /><br />I'll watch thru the Harmy Discs and point out the off red when I see it (even though this is not on CRT). </p>

The idea is that items that were filmed as fire engine cherry red (to show danger for example) were not reproduced as true red in the home (red in the theatre), more like an orange red. But, we perceived it as red in the context of the film, once one sees it though, it is hard to unsee.
