Despite the name of the song, two of the seven colours mentioned ("red and yellow and pink and green, purple and orange and blue") – pink and purple – are not actually a colour of the rainbow (i.e. they are not spectral colors; pink is a variation of shade, and purple is the human brain's interpretation of mixed red/blue [see line of purples]).
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.
ROYGBIV. The conventional gradient colors of the rainbow symbol. ROYGBIV is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo, and violet. When making an artificial rainbow, glass prism is used, but this colors of "ROY-G-BIV" are inverted to VIB-G-YOR".
Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining red and blue pigments. In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both.
In the RGB model, the primary colors are red, green, and blue. The complementary primary–secondary combinations are red – cyan, green – magenta, and blue – yellow. In the RGB color model, the light of two complementary colors, such as red and cyan, combined at full intensity, will make white light, since two complementary colors contain ...

The major, or primary group of colors consists of the sequence of white, red, black, yellow, and violet (mnemonic: Why run backwards? You'll vomit!). The minor, or secondary color is chosen from the sequence blue, orange, green, brown, and slate (mnemonic: Bell operators give better service.).
The most common color mixing models are the additive primary colors (red, green, blue) and the subtractive primary colors (cyan, magenta, yellow). Primary colors can also be conceptual (not necessarily real), either as additive mathematical elements of a color space or as irreducible phenomenological categories in domains such as psychology and ...
