The Color Code Personality Profile also known as The Color Code or The People Code is a personality test designed by Taylor Hartman. [1] Despite being widely used in business and other fields, it is a pseudoscience. [2]
"The brown paper bag test" is a term in Black oral history used to describe a colorist discriminatory practice within the Black community in the 20th century, in which an individual's skin tone is compared to the color of a brown paper bag.

Each sheet of paper has three separate detection dyes.

[1] The M8 detector paper does not detect agents in the form of aerosols or vapors.
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
The ability to discriminate color differences decreases rapidly as the visual angle subtends less than 12' (0.2° or ~2 mm at a viewing distance of 50 cm), [5] so color stimulus of at least 3 mm in diameter or thickness is recommended when the color is on paper or on a screen. [6]
A precursor to the SMPTE test pattern was conceived by Norbert D. Larky (1927–2018) [5] [6] and David D. Holmes (1926–2006) [7] [8] of RCA Laboratories and first published in RCA Licensee Bulletin LB-819 on February 7, 1951. U.S. patent 2,742,525 Color Test Pattern Generator (now expired) was awarded on April 17, 1956, to Larky and Holmes. [9]
