Introduction to DNP Standard Color Bar Test Card

The DNP standard color bar test card is specifically designed to check the color reproduction of TV cameras.

The test card screen area is divided into 6 color bars, displaying the primary colors of red, green, blue, and secondary colors of cyan, yellow, and purple, as well as white and black modules.

From left to right are white, yellow, cyan, green, magenta, red, and blue.

The colors and their concentrations are as follows

Objects selectively absorb and reflect incident light, forming the color of the object. Objects do not have a fixed color, and they can exhibit different colors depending on the composition of the light source.

Complementary color: If two colors of light are mixed in appropriate proportions to produce white and gray, these two colors become complementary colors.

Color subtraction: selectively absorbing certain colors from polychromatic light to obtain the desired color.

Color contrast: The mutual influence of different colors in adjacent areas. Adjacent colors affect each other's results, causing each color to undergo complementary color changes towards its affected color.

The standardized test card provides a great help for adjusting the resolution and color of multiple cameras. We suggest combining the test card with a professional perspective lightbox. The DNP standard color bar test card provides a certain degree of light resistance and weather resistance, which traditional color bar color cards cannot achieve.
