EBU 100/0/100/0 Colour Bars Displayed colours are only approximate due to different transfer and colour spaces used on web pages and video (BT.601 or BT.709). An alternate form of colour bars is the 100% Colour Bars or EBU 100/0/100/0 Colour Bars pattern (specified in ITU-R Rec. BT.1729 [8]), also known as the RGB pattern or full field bars, which consists of eight vertical bars of 100% ...
A PAL vectorscope displaying color bars. A vectorscope is a special type of oscilloscope used in both audio and video applications.

SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America. "In digital video the values of 0 and 255 are reserved for sync" Actually only for limited range, neither full range YCbCr, nor full range RGB have that problem.
Raster bars and similar effects (e.g. having a HUD that uses a different set of colours than does the playing area) are achieved by changing the entries in the CLUT at specific times while the screen is being drawn (originally by the electron beam), in order to display a different set of colours in the subsequent portion of the screen.
