al_color_xyy(3)

💖 NAME 💖

Okay so this is the tea on al_color_xyy — it's part of the Allegro 5 API, and we're reading the al_color_xyy(3) page from the Allegro reference manual (Library Functions Manual vibes, iykyk) 🫶. It's the function that hands you an ALLEGRO_COLOR(3) structure from xyY values, and bestie, the Y in xyY is literally the same Y as in XYZ — no cap.

ALLEGRO_COLOR al_color_xyy(float x, float y, float y2)

✨ DESCRIPTION ✨

So al_color_xyy returns an ALLEGRO_COLOR(3) structure from xyY values. The Y component in the xyY color space is the same as the Y in XYZ. Periodt 💅.

However, the x and y values are computed from XYZ like this, bestie:

x = X / (X + Y + Z)
y = Y / (X + Y + Z)
