When I read this poem, i pitchure a person with a paint brush, painting a gaint white room with wonderful happy bright colors, that filled the room with glow. You did another great job.
This is exquisite, lovely. Original how you associate life with colors (lively colors correspond to positive emotions, dark colors with melancholy, and grey being in between, a neutral color, no?) and how a loved one has a glow, a very vibrant, radiant glow, but unfortunately that glow isn't reflected toward you.
This piece of work reminds me of a Russian pop song quite a bit, at least the first few lines. The chorus of it goes something like this (if I translate correctly):
I would repaint the moon
Into million of different colours
Into a blue wave, into a golden sand
And the sun would be warmer
And would be more radiant than the fire,
The queen of the nights, butterfly-moon
So your work has two different perspectives a positive one and a negative one, but what I like is that the tone of this piece is innocent-like. There is of course discouragement and gloom but there's no harshness, no viciousness, only innocent child-like harmless emotions.
