I like naturally occurring colours.
Colour choices that were made because something had to be chosen. Like the blue screen of an AV camera. A default colour.
Regardless of how it was chosen, that blue is now a part of the cultural vocabulary. Through the prominence of camera technology, all its adjacent choices are now a part of the cultural subconscious.
AV blue is a paintless colour.
It is untranslatable to paint colour theory.
It is defined by its hue, backlighting and pixel scale.
Without backlighting, AV blue is something close to Klein blue.
I would even say that AV blue is only accessible through AV technology. Something to do with the broken pixelisation of the colour making it slightly noisy. The intensity of the backlight.
Pixels on our phones are too fine and are now only imitating the pixels of the AV cameras. 100 pixels making the shape of 1 AV pixel.
Scale is part of colour.
