colour bars
Broadcast calibration stripes
Colour bars are a standardised test pattern of vertical coloured stripes used to calibrate television monitors and video equipment.
The pattern typically includes white, yellow, cyan, green, magenta, red, blue, and black bars, allowing technicians to adjust colour accuracy, brightness, and contrast.
Broadcast stations display colour bars during off-air hours or before programming begins.
Also spelled color bars in American English.
