Last week a prospective customer forwarded us an ad clip: bright blue arrows floating above a street crossing, like a head-up display made for pedestrians. His question was blunt: "why does your display only glow green?" The honest answer isn't a compromise — it's a deliberate choice, and it's worth understanding before you write it off as a limitation.
Short answer: the Even G2 shows a monochrome, green display — not a full-colour image. For the functions that make up most of real-world use — notifications, notes, navigation cues, captions, translated text, teleprompter scripts — sharp, high-contrast text is all you need, and monochrome brings real advantages with it: better everyday readability, lower power draw, a more discreet look. Colour only starts to matter once you're talking about photos, video, or overlaid 3D graphics — and that's not what the G2 is built for.
What the green glow is actually doing
The G2 projects text and simple icons through a small waveguide directly into the lens — technically related to the green head-up displays you may know from certain cars or camera viewfinders. It is deliberately a display overlay, not a screen: no pixel matrix for photos, no video decoder, no colour palette to mix. Even doesn't publish official brightness or field-of-view figures we could responsibly repeat here — what matters day to day is the practical impression: sharp, legible green text floating over the real world without blocking it.
Why green specifically?
Green is a common industry choice for waveguide displays of this kind, because it tends to deliver good contrast at comparatively low power draw — that's a general technical observation about this display category, not an official explanation from Even Realities, which doesn't publish its own reasoning on the point.
What monochrome is genuinely enough for — and where it wins
Almost every feature buyers actually use day to day is, at its core, text or a simple icon:
- Notifications — calls, messages, calendar: plain text, colour wouldn't add legibility.
- Teleprompter — loaded scripts are running text.
- Navigation — an arrow plus a distance figure works just as reliably in monochrome, and often sits less distractingly in your field of view than a colourful one would.
- Translation and captions — text to read, not images.
- QuickNote — spoken notes that appear as text.
Monochrome here isn't the stripped-down version of colour — it's the more sensible choice for a device worn on your face all day. A simpler optical system needs less energy: per the Even Support Center, the G2 runs on a 192 mAh battery for roughly two days of typical use, with the charging case good for about seven full recharges; a meaningfully more complex colour display would be hard to run on that power budget — that's our editorial inference, not a manufacturer statement about a colour option. Then there's discretion: a thin green overlay is barely visible from outside, while brighter, colourful displays tend to stand out — relevant for anyone wearing the glasses in conversation or a meeting without drawing attention.
What you actually need colour for
There are genuine use cases where a monochrome overlay is simply the wrong tool category:
| Use case | What it needs | Is monochrome enough? |
|---|---|---|
| Reading text (messages, notes, translation) | Contrast, sharpness | Yes |
| Navigation cues (arrow, distance) | A clear icon | Yes |
| Viewing a photo or video | Colour rendering, a screen | No |
| Colour AR overlays on the real world (games, product previews) | Colour 3D graphics | No |
| Presentation slides with charts | Basic shape yes, colour coding no | Partly |

When a colour headset is genuinely the better choice
If you want to regularly watch films on the go, follow colour-coded presentations, or use AR games with colourful graphics, the G2 is the wrong address. That's exactly why a different device category exists: colour display glasses with larger, usually darker optical systems that show a full virtual image instead of a slim text overlay. Our comparison overview sorts the main models by exactly this question.
If, on the other hand, most of your day is text, cues, and translation — and you want to stay light, discreet, and easy on battery while doing it — monochrome isn't the worse option, it's the better one. Whether the G2 fits your day-to-day is covered in our overview of who the G2 actually suits.
Buy, skip, or test first?
Buy with a clear conscience if your daily use is notifications, notes, navigation, translation and teleprompter text, and discretion plus battery life matter to you. That's exactly what the G2 is built for.
Skip it — or choose a different category — if your main reason for wanting a display headset is colour media, AR overlays, or games. No software update turns a monochrome waveguide into a colour screen after the fact.
Test before buying the one thing no spec sheet shows: how the green display actually reads in your own environment — in daylight, indoors, at the text size you're used to. A short test at our Zurich showroom, or a look through the AI glasses database comparing every model, helps set expectations before you commit.
Disclosure: AI-Eyewear is the authorised Swiss reseller of Even Realities. Where a colour headset is genuinely the better choice, we say so as plainly as here — and point you to the right category rather than promise a feature the G2 doesn't have.
