Before you start

Logo evolution means comparing an older version of a mark with a later version to see what changed. The examples here are fictional demonstration marks, so they can be viewed as prompts for your own comparisons rather than as a claim about any real company. You do not need special software or a camera; you can do this in a browser with two image files or with the source files that make up the mark.

Use a lossless or high-quality image where possible. A heavily compressed photograph of a printed logo can blur fine details or change colors. If you are comparing files you made yourself, keep the original exported versions rather than screenshots. If you are working with a provided example, note whether the image has a transparent background or a solid background; that changes how spacing and contrast appear.

Keep the comparison reversible. Make a copy of each version before trying edits, overlays or color changes. Do not replace your only exported file with a test version.

Step-by-step instructions

  • Open two versions of one mark. Place them side by side at the same display size. If the older version is only available at low resolution, compare it with the newer version scaled to match the same visible height.
  • Check the silhouette first. Cover or blur the details until only the outer shape remains. Note whether the outer shape has become simpler or more compact.
  • Check the number of colors. Count the color fields in each version. A common change is a move from several highlight colors to fewer flat colors.
  • Check outline and contrast. Look at whether outlines were removed, thickened or replaced by larger contrasting areas.
  • Check the wordmark. If the mark has letters, compare weight, spacing and case. Note whether the name became the main element or the symbol became the main element.
  • Check small-use details. View both versions at roughly 16 to 24 pixels high or at a small preview size. Note which parts disappear, crowd together or lose contrast.
  • Note intent, not just difference. Mark down whether each change appears to support recognition, one-color printing, mobile use or clearer spacing.

Check the output

A useful comparison should let you describe three points: what changed, which constraint the change likely addresses and which detail still needs checking at a real export size. If you only list visual differences without a reason, the comparison is incomplete.

For an image file, verify the expected format and size after any export. If you are comparing in a mockup or on a colored background, check the mark on both light and dark fills. A logo can look legible on white but fail on a saturated background, so the pair is only verified when both cases are readable.

Do not treat an example as proof that a particular change works for every brand. A change that helped one mark may not help another mark with a different silhouette or name length.

Common problems and next steps

The versions look different only because of resolution. If one image is blurry or compressed, do not call that a design change. Check the file dimensions and whether the source was a screenshot rather than an export.

The colors look unlike the intended palette. If the image uses a different color profile or has been converted, compare numeric color values rather than relying on display appearance. For an uploaded image, read the color values in the palette tool instead of judging them from a photo.

A detail survives at full size but disappears at small size. This is a common signal that the evolution succeeded only partially. Check the mark at the smallest real use size before deciding that the redesign is finished.

The comparison feels subjective. To make it practical, keep the same background under both versions and place them at the same height. Then rate legibility, edge clarity and color count separately instead of trying to decide which version is better overall.

If you are preparing a redesign, use the before and after slider on this site to compare the original and proposed versions in one view. Keep the original version unchanged and work on a copy first.
