v. t. e. The handkerchief code (also known as the hanky code, the bandana code, and flagging) [1] is a system of color-coded cloth handkerchief or bandanas for non-verbally communicating one's interests in sexual activities and fetishes. The color of the handkerchief identifies a particular activity, and the pocket it is worn in (left or right ...
Shades of orange. In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure.
The first letter of the color code is matched by order of increasing magnitude. The electronic color codes, in order, are: 0 = Black; 1 = Brown; 2 = Red; 3 = Orange; 4 = Yellow; 5 = Green; 6 = Blue; 7 = Violet; 8 = Gray; 9 = White; Easy to remember. A mnemonic which includes color name(s) generally reduces the chances of confusing black and brown.
The IALA recommends categorical color codes in 7 colors: red, orange, yellow, green, blue, white & black. [4] Adding redundant coding of luminosity and colorfulness adds information and increases speed and accuracy of color decoding tasks. [3]
Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red.

The colors are sorted in ascending order of frequency to make them easy to remember and to reduce the significance of possible read errors due to color shifts and fading over time: red (2), orange (3), yellow (4), green (5), blue (6), violet (7). Black (0) has no energy, brown (1) has a little more, white (9) has everything and grey (8) is like ...
