Prime counting
Gold1
Exact interval prime counting with a dedicated Count Primes workflow and evidence-first benchmark tooling.

A family of engines.
Not a black box.
Chromatic Engines presents distinct numerical projects through one commercial identity while keeping their scope, evidence and implementation boundaries visible.
IDENTITY
Why chromatic?
The colour system is functional: every engine keeps a stable visual identity across public presentation and internal orchestration.
Prime sieving
Red2
A high-performance prime-sieving research engine developed around explicit validation and reproducible measurement.
Explore Red2 →Prime search
Blue3
A structured large-prime candidate/search project whose public surface separates observed results from conjecture.
Explore Blue3 →Gravity research
Violet4
A research-preview numerical framework for gravity experiments, with model assumptions and validation kept explicit.
Explore Violet4 →BUILD PHILOSOPHY
Built in stages.
The commercial platform is deliberately phased so presentation does not get ahead of security, licensing, compute controls or legal review.
Public site first
Static product communication can remain available even if the workstation is offline.
Private compute later
Remote work is connected only after worker, database, licensing and security gates exist.
Commercial rights stay explicit
Ordinary product access never silently becomes source access or IP transfer.
