Why, and how, it was made
daycolor is not a fortune-telling service. It is a small project that calculates a saju chart — the eight characters formed from the year, month, day, and hour of your birth — and helps you look at it as a single image and a short verse. What follows is a quiet note on why this exists.
My first meeting with saju and the I Ching came not from scholarly conviction but from curiosity. Notes scribbled in the margins of many schools' books turned, one day, into the thought: "what if I could see this as a picture?" I wanted to make not a tool that hands you an answer, but a window through which you might look at yourself from a step away.
It does not treat this tradition as a prophecy that fixes the future. Rather, it is closer to a map — the natural coordinates of the moment you were born, the grain of season and time, written in an old language. A map does not choose your road. It only shows, plainly, which season you now stand in; how you walk from there is always the reader's own.
Your chart is yours. So here you may copy it at any time and use it freely elsewhere — in another tool, or in a conversation with someone. It does not hold you toward a paid reading or a consultation. This is meant to be one reference among many, not the final word.
Each result is built from the chart's calculation, woven together with colour, image, verse, and the symbols of the seasons. The verses come from the Jiaoshi Yilin, a Han-dynasty oracle, and what reaches you shifts with the date and moment you visit. So a result is less a verdict handed down once than a conversation that changes a little with time. The way it is made is set out more fully on the How it works page.
AI lent a hand with translation, image generation, and some drafting of explanations. But the verses themselves are not invented by AI — they come from a classic — and the wording and commentary pass through human review. The question that matters here is not "did an AI make it?" but "where did this line come from?" That is why the sources are named as far as possible.
It does not stir anxiety or predict the future as a certainty. It does not funnel you toward a paid consultation, nor use fear to prompt a payment. It never says "this will surely happen." This is not a place that sells fortunes, but one that hands you material for looking at yourself.
Please do not take the images and verses met here too heavily. If a line speaks to you, keep it as a companion for the day; if not, let it drift by. And if you have grown genuinely curious, the real study of these traditions is worth doing yourself. This is enough if it is a small signpost at the door.
