Many things that are not blue become blue in our imagination.

Like Van Gogh’s Irises — the blue we now see carries countless meanings, though it was not painted blue at first.
Or like the sea and the sky, which appear blue to us, not because blue truly exists within them.

The visible spectrum of blue light lies between 606 and 668 terahertz.
So perhaps what we call beauty is only an illusion, a filter —
or perhaps it is love, shaped by the longing that gives it color.

Blue is what the world rarely offers, and what the soul always seeks.
Blue shadows, blue light, blue dreams, blue water, blue smoke, blue air.
Blue is the feeling that remains, long after the moment leaves the place.
