Zodiac compatibility and birthday colors: what is different?

Searching for astrology compatibility, a star sign match or a zodiac compatibility test? Green Flags offers a different birthday comparison: a continuous color wheel with a transparent trait-based rule.

Does Green Flags calculate zodiac compatibility?

No. It does not calculate zodiac signs, natal charts, planetary positions, ascendants or synastry. You do not need a birth time or birthplace. The wheel should not be read as an astrological chart.

The day and month map onto a 366-day reference calendar. A date near the start of the year sits near the top of the circle, and the hue changes continuously through the year. February 29 has its own position. The year is retained for age comparisons.

What does an opposite birthday mean?

The dashed diameter marks the hue opposite your birthday: a 180-degree gap on the calendar wheel. This is a visual opposite, not a claim that two star signs make an ideal match. The percentage separately rewards birth months farther apart around the year.

Why does my profile color differ from my birthday color?

Your birthday starts the calculation; your six answers adjust hue, saturation and lightness. The ring remains a birthday map. The comparison swatches show final profile colors. Changing a trait can change your HEX without moving your birthday on the ring.

Can I explore a birthday range?

Drag along the ring with a mouse or finger. The catalogue keeps people whose birthdays are inside the sector. A range can cross December and January. Combine it with age and gender filters, or choose Clear sector to restore the wheel.

Does this predict relationship success?

The tool does not establish that astrology or a color score predicts a successful relationship. Its own output is intended for entertainment and comparison. Explore a visual pattern or start a discussion; do not use it as evidence of romantic or genetic suitability.

Use the manual profile to enter a second birthday and self-reported traits. Public figures have sourced birthdays, while their assigned traits are simulated.
