Blēo, meaning: a colour, hue, complexion in Old English.
Colour is a reflection of light, and light is everywhere we look. It is contextual and our individual experience of it subjective. Our perception of colour is a dance between light and context, a reflection that is ephemeral. That is what makes it so fleeting and hard to grasp. Just as moods change, light changes too, it is the only fact we can rely on.
