In short. Green marks likely similar web content, orange marks differing or missing relevant content, and unhighlighted text can be unevaluable or non-factual.
Definition: Gemini's double-check highlights describe how statements compare with content found through Google Search. Green indicates likely similar content; orange indicates likely different content or no relevant result; unhighlighted text can lack enough information for evaluation or convey non-factual content.
The color definitions follow Google's help page preserved on 28 January 2026. The current help page covers related sources and omits the double-check instructions.
Key facts
- Google's Workspace announcement, dated 4 September 2024, describes double-checking as using Google Search to highlight statements corroborated or contradicted on the web.
- Technology publication Digit's April 2026 guide describes the control under the response's menu with the three dots, labeled Double-check response.
- Google's current sources help places the Sources button below or within a response, opening relevant links in a panel on the right.
What does each highlight mean?
Google's archived double-check help defines these categories:
| Appearance | Meaning | Link behavior |
|---|---|---|
| Green highlight | Search finds content likely similar to the statement. | A link accompanies the result. |
| Orange highlight | Search finds content likely different from the statement, or finds no relevant content. | A link appears if available. |
| No highlight | Information is insufficient for evaluation, or the statement has no factual purpose. | The instructions describe clicking highlighted statements to inspect findings. |
Orange therefore groups differing evidence and missing relevant evidence together. Unhighlighted text also needs interpretation: the category includes statements that are outside factual evaluation.
How are the findings inspected?
Digit's press guide describes opening the menu beneath an answer and choosing the checking option. Its green-highlight instructions direct the reader to click the text to view the source.
For a website review, the useful next step is to read that linked page alongside the precise statement being checked. In particular, an orange result calls for distinguishing a conflicting passage from a search that finds no matching material. Digit explicitly recommends further checking for orange highlights.
Does a green link identify the original source?
Google's archived instructions state that the green link may differ from the material used to generate the response. A website appearing there serves as comparison evidence for the checked statement.
For an agency recording a client's appearance in Gemini, the link's role matters. A review record should identify whether the page appears in a double-check finding or through the Sources interface. That distinction preserves what the observation actually shows.

FAQ
Does orange mean the statement is false?
Orange can also mean that Search finds no relevant match, as Digit's color explanation reports. You need to inspect the finding before deciding how to treat the statement.
Why is there no Sources button beneath my answer?
Google's sources documentation says that some responses contain no related links or sources. If your response lacks that button, Gemini provides no links for that particular response.
