Today's prompt is "spectrum."

I am going Hard Mode on this prompt, as the term has a few different meanings, all of which bear weight to me. I will only be talking about two of them.

A rainbow forming in the sky in the midst of a rain shower (especially on a spring day) always brings me joy, even if I know it is ephemeral. The moment it forms, and the moment I look at it -- these stay with me forever. I have captured some pictures of rainbows and double rainbows in my time before they disappeared. As such, I've made it a tender song, to express that ephemeral joy and brightness, and also the sad understanding that it physically doesn't last -- but also the hope within me that it points towards things that do last.

And -- this is where Hard Mode kicks in -- I mentioned in a thread I'd created that I label certain instrument families with different colours. I made sure to use each colour in the spectrum when composing this, but because I'm terrified of even agitating the neighbours, I've had to rely on a MIDI guitar and BBCSO / VSCO / Flex percussions instead of playing my own strings and percussion. So, in order of spectrum colours:

• Red: cymbals, windchimes
• Orange: bowed strings
• Yellow: horns
• Green: piano, harp
• Turquoise: melodic synth
• Blue: guitar
• Indigo: basses
• Violet: piccolos, flutes, oboe, bassoon
• Magenta: xylophone, glockenspiel
