I made 2 new verses and a new chorus and made the song a little longer, and also added backing vocals, strings, piano and drums in that order. I didn't think it needs drums but when I messed around real quick it really gave it a little nice oomph, so I kept em. But what I'm proud of is that the melody works super well a capella as well. and I really like to play/sing this song, it really makes me happy it's so silly and quite fun 
I hope you enjoy it tooooooooo
‹ More about the process
Featuring Horatiu the keyboard drummer without a metronome. More on that later.
I played a few times the original song since last sunday, and I found it to be a bit too short for my taste so I thought what could I add. Is there anything more to say about this topic? I came up with more stuff that's "colors in the sky" which ended up being butterflies, and also made a verse about how what's in your mind ends up being what seems real to you and what affects your life, and how maybe sometimes you can try to look at the world for what it is, simply and maybe painfully so.
I am not sure the depth of the lyrics comes across but I think there are quite a lot of nice layers to be discovered in all the different verses and choruses. For me it means something quite particular but I think for everyone it will means something else, as it usually goes.
I don't know on the solo guitar and voc version how to make the verses more distinct - that's one of the reasons I went with piano from verse 2, bg vocs on chorus1, strings on v3 and drums on v4 - so every verse has something new to add to make it fresh. It probably works fine more monotonous but I took some inspiration from that interview with Rick Rubin where he talks about how much little stuff he adds to some Tom Petty tune, so that every verse is new and fresh. I haven't studied it carefully and I think in many productions the vocals are also a big part of what makes every verse different, when the vocalist can do some more wacky things - I am a bit limited in my technique so I didn't wanna fool around for this song.
Strings were kinda tricky to do, but managed. Lots of fake counterpoint since I don't know how to properly do that. but I went with what sounded good on piano and tweaked it a lot on the piano roll. string sounds coming from the sv-2s.
Finally, the drums - I recorded everything by hand in this order: hi hat, kick drum, the fills w/ snare and toms, the regular snare, then the wacky cymbals. The song was not on a metronome so it was extra annoying to tweak little things in the beat. Mostly I did it by ear rather than by looking at the piano roll.
Sprinkled liberally with nice plugins from UAD such as the new A-type multiband dynamic enhancer (dunno what the hell this does but makes everything sound better so it's on the drums, vocals, guitar, everything basically).
not sure about the production, I think it sounds fine tho a little bit cooked. I hope I won't hate it later cause voc is too loud.
‹ Lyrics
[verse 1]
Why are rainbows upside down?
oh, their colors are not suited for a frown
I imagine how they got this way
cast away by the sun
run away from everyone...
[verse 2]
Seems it's always raining here
(but the) clouds are only rainbow stashes in the air
and the rain will surely stop someday
and my dreams will all come true
maybe rainbows made the sky so blue...
[chorus]
and maybe
it's wrong to judge the colors in the sky
when all of them are refracted in my eye
and up and down
feel different when you're floating off the ground...
[verse 3]
on the wings of butterflies
shapes and colors make a beautiful disguise
while they're flapping catastrophically
goes to show that all beauty
is a form of trickery
[verse 4]
things the mind believes are real
really are, as they affect how you feel
oh, the mind is such a mystery
overthinking constantly
things are often what they seem to be...
[chorus2]
so maybe
it's wrong to judge the wings of butterflies
when all of them try to live their little lives
and up and down
feel different when you're floating off the ground...
