SMPTE Color Bars Test - Professional Calibration Pattern
This color bars test displays the classic SMPTE standard pattern used in broadcast television since 1978. The sequence of vertical bars (white, yellow, cyan, green, magenta, red, blue, black) tests all primary and secondary colors plus full brightness range in one comprehensive pattern. Use it for quick color accuracy checks before video editing sessions, to verify signal integrity, or as a reference when calibrating your display settings.

✅ How to Use Color Bars
- • Check that each color appears distinct and pure
- • Verify clear boundaries between adjacent bars
- • Compare white and black for contrast ratio assessment
- • Look for color casts or shifts indicating calibration issues

How to Use Color Palette & Display Tester
Starting the Color Bars Test
Click "Start Color Bars Test" to display the SMPTE-style color bar pattern in fullscreen. The pattern shows 8 vertical bars: white, yellow, cyan, green, magenta, red, blue, and black from left to right.
Checking Color Accuracy
Compare each color bar to your expectations. Yellow should be pure yellow (not orange), cyan should be distinct from both green and blue, magenta should not lean toward red or purple. Color casts or shifts indicate calibration issues.
Verifying Color Separation
Each bar should be distinctly separate from its neighbors with clear boundaries. If colors bleed into each other or boundaries appear fuzzy, this may indicate resolution issues or signal problems.
Assessing Brightness Range
Check that white appears bright and clean, while black appears as deep black as your display can produce. The contrast between white and black bars indicates your display's dynamic range.

Common Calculations & Examples
Example 1: Pre-Session Color Check for Video Editing
Problem: You need to verify your monitor colors are accurate before starting a video editing session
Steps:
- Display the color bars test pattern in fullscreen
- Verify white appears neutral without any color tint
- Check that yellow, cyan, green, magenta, red, and blue look distinct and saturated
- Ensure black appears as deep black with no gray tint
- Verify clear boundaries between each color bar
Explanation: Color bars provide a quick sanity check that your display hasn't drifted from calibration. Any obvious color shifts or muddy boundaries indicate calibration issues.
