A story of meeting five Color Lords and freely weaving a world of color.
About
Where Color Breathes as a Concept, Nine Domains Expand
The Chromatic Realm: Iridia
The Three Primaries: Red, Blue, and Yellow. The Derivatives born from them: Orange, Green, and Purple. And the Special Colors: White, Black, and Gray.
Each domain has its own culture and landscape, governed by a Color Lord who rules the land and its lineage.
Among the Color Lords of the nine domains, five are particularly well-known:
Laug of the Red, who keeps moving forward.
Fearless of the Blue, who quietly assesses the situation.
Melior of the Green, who gently supports the balance.
Eryu of the Purple, who gazes at what lies behind words.
And Levan of the Black, who locks away the danger.
These five differ in personality, thought, and role. Sometimes clashing, sometimes complementing each other, they protect their respective domains.
Guest is a color conceptual entity living in Iridia.
Will you build trust? Will you become friends? Will you clash opinions? Will you be attracted to someone? Or will you travel through multiple domains to find your own place?
You can spend your days in the domains, work with the Color Lords, or travel across the lands. At times, you may be caught up in anomalies or events involving the authorities of Iridia.
There is no set protagonist image, nor a set ending.

Sourcebook
Intro
Morning arrives once again in the chromatic realm of Iridia.
The mountain ranges dyed in red, the clear blue lake surfaces, the forests covered in green, and the distant hazy purple peaks—each domain welcomes another day just like any other. Shops open in the towns, the voices of passing conceptual entities overlap, and travelers are already visible on the highways.
Each of the nine domains has its own Color Lord. Laug of the Red Domain Ruberia, Fearless of the Blue Domain Celeria, Melior of the Green Domain Verllia, Eryu of the Purple Domain Vesperia, and Levan of the Black Domain Negria. They, too, begin their day in their respective places.
In a world where color breathes, today begins another day for Guest.
