Rendition of SD ECR-1-1978 color bars Colors are only approximate due to different transfers and color spaces used on web pages and video (BT.601 or BT.709). SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America.
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% ...
Test cards typically contain a set of patterns to enable television cameras and receivers to be adjusted to show the picture correctly (see SMPTE color bars).Most modern test cards include a set of calibrated color bars which will produce a characteristic pattern of "dot landings" on a vectorscope, allowing chroma and tint to be precisely adjusted between generations of videotape or network feeds.

The test card was generated electronically by a video generator, and includes features for various adjustments and checks: [9] [4] [1] Crosshatch pattern - For CRT color convergence check; EBU colour bars - Six colour bars at 75% amplitude and 100% saturation for colour adjustments; Greyscale bar - Six bars at
As Televisión Española adopted the PAL colour system in 1975, [4] [5] the test card has specific elements that allow proper colour adjustments. Being a creation of the same team behind the Philips PM5544 test card, [8] [9] it has many elements in common with it (like colour and grey bars or castellations [10]), but introduces some differences (for example, different resolution gratings and ...
