01 / Quiet control
Everything the lights need.
Nothing they don’t.
SteelSeries GG is a multi-hundred-megabyte suite. Reflective is a focused menu-bar utility that speaks the Arena 7's USB language directly—fast to open, simple to understand, and out of your way.

02 / Screen Sync
Your screen,
spilling into the room.
Reflective samples four regions of the display and sends their colors to the Arena 7 in real time. Choose narrow edge strips for bias lighting or full quarters for a wider wash.

Edges or quarters
Sample slim outer strips for a focused ambilight effect, or divide the full display into four broad regions.
Content-aware framing
Letterbox and pillarbox bars are detected and trimmed so black borders do not mute the colors that matter.
Smooth and efficient
Color ramps stay fluid while capture rate automatically backs off when your Mac is under thermal pressure.
03 / The full spectrum
Small app.
Wide range.
Every control is designed for the menu bar, from a custom inline color picker to live screen sampling.
02
Independent zones
Choose left and right colors independently. Each speaker drives its base and rear LEDs as a pair.
03
Wallpaper palette
Extract a palette from the current desktop wallpaper and send a favorite pair to the speakers in one click.
04
Native controls
Inline color picker, hardware brightness, power, launch at login, and update checks—all inside the menu bar.
05
Direct USB HID
Reflective talks directly to the Arena 7. No SteelSeries GG process, account, cloud, or background service required.
06
Tiny by design
A focused, native SwiftUI utility around 1 MB. Signed, notarized, and built for macOS 14 or newer.
04 / Direct connection
One tiny packet.
Four zones of color.
Arena 7 exposes a vendor HID interface at 0x1038:0x1A00. Reflective sends a 64-byte Output report straight to the hardware—no vendor daemon in the middle.

05 / Built forward
Reflective began with Prismatic.
Reflective is a fork of Prismatic for macOS, whose creator reverse-engineered the Arena 7 USB lighting protocol and built the original app. That foundational work remains credited upstream and made everything here possible.
Jezz Lucena continues the project as Reflective—with a new identity, active releases, and Screen Sync.
