Song recommendations on Deezer: determine mood using colors semantics

Once, using this colour test, I noticed that my mood coincided with one of the Beatles' songs

You can find the test version here:
Here you can find the test and simpliest MVP of music recommendation system how it can be created (MUSLI stands for Musica Lingua or Music Lingo):

The sequence of passing the test is simple:
1. Which of the eight colors seems the most pleasing?
2. Which of the remaining colors seems the most pleasing? (until all the color cards go to the result)

A little theory with illustrations


Also I found the following:

Scientists from the University of California, Berkeley, found that music and color are connected through an intermediate link - emotions


There is a research about how colours can express emotions:

Since the interpretation text can be translated into any language in the world, this makes music a universal language.

Jim Carrey about music:

Also listen to three songs from Paul McCartney's Flaming Pie album:

1. The Song We Were Singing

2. The World Tonight

3. Great Day



And so here are some examples of matching the first pair of colors of the test and the songs:

Your Desired Objective
"Wants to sweep aside the things that stand in his way, to follow his impulses and be involved in special or exciting happenings. In this way he hopes to deaden the intensity of his conflicts, but his impulsive behavior leads him to take risks":

1. The Clash - London Calling
2. Ozzy Osbourne - Crazy Train

Your Desired Objective
"Seeks affectionate, satisfying and harmonious relationships. Desires an intimate union, in which there is love, self-sacrifice and mutual trust":

1. Echo Jet - Something To Believe In
2. The Beatles - All You Need Is Love

As you can see the author creating a song partially duplicates the information transmitted through the text channel (verbal) and the intonation channel of the music (non-verbal)

Thus the song form is an implementation of Jung's Transcendent Function. As much as Max Lucsher's color test too

"There is nothing mysterious or metaphysical about the term "transcendent function". It serves to denote a psychological function comparable in nature to the mathematical function of the same name that connects real and imaginary numbers. The psychological "transcendent function" is the result of combining conscious and unconscious contents"

Also, if we put on the 7th and 8th place two colors, when mixed, it turns out the "the ugliest colour in the world" (, then we get the following interpretation:
"Has an unsatisfied need to ally himself with others whose [ethical]standards are as high as his own, and to stand out from the rank and file. This subjects him to considerable stress, but he sticks to his [ethical]attitudes despite lack of appreciation. Finds the situation uncomfortable and would like to break away from it, but refuses to compromise with his [ethical]opinions. Unable to resolve the situation because he continually postpones making the necessary [ethical]decision, as he doubts his ability to withstand the opposition which would result. Needs the esteem of others, compliance with his wishes and respect for his opinions before he can feel at ease and secure"

Paul McCartney - Cosmically Conscious

An interesting thing: if you change four pairs of colors in places, while maintaining the order inside the pairs, then from Love intonation from "All You Need Is Love" you can get Joy from "Cosmically Conscious" an Us intonation from "Imagine" ^_^

Today’s mood:

“Your Desired Objective: Seeks an affectionate relationship, offering fulfillment and happiness. Capable of powerful emotional enthusiasm. Helpful, and willing to adapt himself if necessary to realize the bond of affection he desires. Needs the same consideration and understanding from others”

or (the same first two colors, but in a different version of the test)

“Looking for a loving relationship, which brings happiness and contentment. Brings emotional excitement to the relationship. Helpful and willing to give as much as he takes, and requires the same sort of giving relationship from others”

Amy Macdonald - Human Spirit

The Beatles - Fixing A Hole

Electric Light Orchestra - Mr. Blue Sky

Hi @Musli, thanks for sharing these links, I'll be doing my colour mood as well! 

This is a great idea! Not sure how Deezer can implement this, but I'm happy to pass it on to the right team! ;)

I will be happy to provide additional data for analysis and insights: more examples on which you can establish patterns. Deezer wrote the following library which allows you to divide the composition into separate instrumental parts (including the vocal part). Next, you can set the musical tone for each individual part: here is the service which allows you to automatically detect this information. In other words, this possibility is realizable. It is possible that something similar is already being used inside Deezer: I'm talking about automatically detecting the tone of a song. The fact is that the musical form is related to the musical content. Therefore, the first color of the eight is probably set by the key of the musical part (each of the 8 colors corresponds to 3 keys).
