Gemini logo redesign: before-and-after evaluation
An evaluation of the Gemini logo redesign: what changed in the spark mark, why it matters for vector artwork, and what to check before using or editing the files.
Contents
The short answer
The redesign concerns Google's Gemini AI assistant and the four-pointed spark symbol that represents it. In the earlier version, the spark used a cool blue-to-violet gradient. In the redesign, the spark keeps its basic four-pointed form but adopts a multicolour gradient. That gradient draws on Google's familiar red, yellow, green and blue palette. The change was publicly reported in 2025, alongside a similar gradient refresh of Google's own G icon.
Editorially, the effect is to move Gemini from a standalone product identity toward a visible place in the core Google family. No source documents, official brand guidelines or original artwork files were supplied for this article. Exact dates, colour values, geometry changes and the current status of the mark should therefore be confirmed against Google's official brand resources before you rely on them. Further revisions may also have occurred since this assessment was prepared.
Before and after at a glance
| Aspect | Earlier Gemini mark | Redesigned Gemini mark | Evidence status |
| Symbol | Four-pointed spark | Four-pointed spark, broadly retained | Widely reported; precise path changes not verified here |
| Colour | Blue-to-violet gradient | Multicolour gradient referencing Google's red, yellow, green and blue | Widely reported; exact colour stops not supplied |
| Brand relationship | Distinct product look | Closer alignment with the Google G icon refresh | Editorial interpretation |
| Wordmark | Gemini name set alongside the spark | Not confirmed from supplied material | Gap: verify against official assets |
Evaluation: what the redesign gains and costs
The following points are editorial judgments, not measured results. The main gain is coherence. A user who sees the spark next to Google's other icons can now read it as part of the same family. The earlier blue-violet treatment had a calmer, more singular character that set Gemini apart. Some of that distinctiveness is traded away for brand unity.
The cost lies in reproduction. A gradient that blends four hues is harder to hold together at very small sizes than a two-tone gradient. It is also harder to reproduce on low-quality screens and in limited-colour print. Whether Google provides flat, single-colour or monochrome versions for those contexts is not established by the supplied material. That is a gap worth checking in the official guidelines.
What this means for vector artwork
Gradients are where vector logo files most often turn out to be less editable than they appear. SVG and common design formats can store linear and radial gradients as true vector instructions, and those remain scalable and editable. However, a complex, multi-directional blend is sometimes exported a different way: it may arrive as an embedded raster image clipped inside a vector shape, or simply as a raster preview. In those cases the outline may scale cleanly while the colour fill pixelates or cannot be adjusted.
- Open the file in a vector editor and confirm that the spark is built from paths, not a placed image.
- Inspect the fill: a native gradient shows editable colour stops, while an embedded bitmap shows as a linked or embedded image object.
- Do not assume a file is editable vector artwork because it ends in .svg, .eps, .ai or .pdf; these formats can all contain raster content.
- Check whether the file you have reflects the earlier blue-violet mark or the redesigned multicolour version, since both circulate widely.
Permissions: downloading is not the same as modifying
The Gemini name and spark are Google trademarks. Being able to download a logo file, even from an official source, does not grant permission to alter its colours, reshape the spark, or recreate it in a different style. Using it to imply endorsement or partnership requires separate permission too. Any typeface in the wordmark may also carry its own licence terms. Google's brand guidelines and trademark policies govern acceptable use, and their specific terms for Gemini were not part of the supplied material.
Open questions to resolve
- The official date and announcement details of the redesign.
- Exact colour values and gradient stop positions for both versions.
- Whether the spark's geometry changed in proportion or curvature, not just colour.
- Which official file formats are offered, and whether they contain native vector gradients.
- Availability of flat or monochrome variants for small or limited-colour use.
