Compatibility score
Contrasting colors — a stimulating, dynamic bond.
Score derived from the 115° hue distance between the two colors (0°→100, 180°→0, linear, minimum 5; when either color is achromatic, brightness distance is used instead). Not fortune-telling — a transparent formula.

How it works (algorithm disclosed)
Each birthday color is read as a hue on the HSL color wheel. The smaller the hue distance, the higher the score; opposite colors score lowest. The memorial color is the RGB average. Anyone can reproduce the same result — that transparency is this site's policy.
FAQ
How is the compatibility score calculated?
From the hue distance (0–180°) between the two birthday colors: a linear scale from 100 at 0° to 0 at 180°, with a floor of 5 (achromatic colors use brightness distance instead). It's a transparent formula anyone can verify — not fortune-telling.
Does a low score mean we're incompatible?
No — it only means the colors are far apart. Contrasting colors highlight each other; read a low score as stimulating, not bad.
What can I do with the memorial (mixed) color?
It's the average of your two colors. Copy the HEX for anniversary wallpapers, matching outfit accents, or gift wrapping.
Is it free? Do I need to sign up?
Free, no sign-up. Everything runs in your browser — birthdays are not stored on a server, and the month/day parameters in the shareable URL are stripped by the analytics tags before transmission.
