About Stains of Blue

Stains of Blue is an adult visual novel created by Zetzsuu using Ren'Py. Its presentation uses 2D AI-generated CG artwork and animated intimate sequences. You play a male protagonist who guides a heroine through stories centered on netorase. The game lets you choose one of five blue-themed personalities, from gentle Aquamarine to commanding Cobalt, and combine that choice with different relationship dynamics. Character creation, corruption, and interracial themes are part of the experience.

Development is finished at v1.9, released July 13, 2026. The build runs on Windows, Mac, Linux, and Android, in English, without censorship. The latest update rebuilt the game with new assets, added extensive polish, and made the presentation more cinematic, with more animated video files than static images.

Changelog

In fact there's so much polish it reflects more light than a bald man's head on a sunny afternoon. - Completely immersive, cinematic experience. Fun fact, there are more video animation assets than there are static images in the game files. - This will be the final update before the actual post prologue content. I swear! No more retreading back. - Game is basically AAA quality now (allegedly) v1.6b -The screen that shows why Cobalt + Pimp are not compatible will now display properly. -Fixed missing images for Blue Pubic hair banners during the review screen. -Fixed the reported typos and spelling errors on the Cobalt path given by users. -Fixed bug during skip where sometimes the sprites wont correctly render in/out after getting out of skip. -Added a new sprite callback system from the backend that hopefully reduces some lag and improve performance. -The sprites now slightly zoom in/out and get highlighted depending on who is the current speaker, to make it more clear who is speaking. v1.6 -Parallax/Panoramic view added into the game.
