Before you start

This task is about comparing visual logo versions, not about editing a live brand asset. Work with copies of image files you already have or can obtain legitimately. The review can be done locally in any image viewer or browser, so there is no service required. If you plan to measure contrast or palette, use a tool that operates on the image itself rather than assuming values from memory.

Step-by-step instructions

Place the older and newer logo versions side by side at the same display size. Align them either horizontally or vertically so the comparison does not depend on one image being larger. Keep the original files unchanged and work only with duplicates if you need to crop, zoom, or mark the image.

Look first at the overall silhouette and background. Note whether the logo is a wordmark, emblem, or combined mark, and whether the background color has been simplified. Then compare letterforms, line weight, spacing, and any mountain or sky elements that have been redrawn.

If color is important to the review, create a small set of swatches from each version. Sample the main background and any visible graphic elements. Write down the samples as approximate descriptive values rather than presenting them as official brand colors unless you are reading them from a verified source file.

If you use a before-and-after slider, place the older version on one side and the newer version on the other. Slide slowly across the main brand element so the change is easy to see. Avoid moving the images independently, because that can create a false impression of one version shifting position.

Check the output

Confirm that both versions are visible at the same scale and that details such as edges, gaps, and small shapes are not hidden by compression. If you export a comparison image, use a lossless format such as PNG for the review. A screenshot or heavily compressed export can make fine redraw changes look like noise.

Common problems and next steps

A frequent issue is drawing conclusions from images that have different resolutions or background fills. Resize both to the same height and compare them on a neutral background before judging proportions. If the versions use different color profiles, note that displayed color may shift, but do not invent specific percentage differences.

Another useful correction is to focus on one change at a time. For example, check the wordmark shape separately from the mountain graphic, then check their relative spacing. If a local source file or official usage guide is available, verify the findings against that source before calling any detail a confirmed brand change.
