BVB Logo History: Evaluating Changes Across Versions

Before you start

This task is about inspection and comparison, not editing. You only need two color images or screenshots of different BVB logo versions. If you plan to measure color, contrast, or spacing, check whether your image tool reports pixel values or requires a separate color picker; do not assume a feature exists.

For fixture or template work, keep the originals unchanged and compare on copies. If you are working with a screenshot from the web, note the page title and capture date so the source version remains identifiable.

Step-by-step instructions

• Open the older logo version and crop it to the mark only, without extra padding.
• Open the newer logo version and crop it in the same way.
• Place both crops on a neutral background rather than a busy photo.
• Resize the newer crop to the older crop's width if the aspect ratios are close; if the geometry differs strongly, keep the sizes separate.
• Use the compare view or a simple two-layer stack to switch between versions.
• Check the most visible changes first: outer shape, wordmark, spacing, and added or removed elements.
• If color changed, compare the fills in similar light and note whether any color space conversion is visible.
• If thin details changed, inspect at a larger zoom or export a larger preview from the original vector file if one is available.

For a reversible before-and-after comparison, some tools provide before/after sliders or layer opacity controls. If your application does not have a built-in history slider, use two layers and toggle the top layer's visibility.

Check the output

Confirm that both versions are shown at a comparable scale and that no cropping accidentally removes the part being compared. The expected result is not a good or bad logo judgment; it is a clear record of which elements changed.

If you are producing notes or labels, keep them tied to what is visible. State "the gap between the letters appears wider" rather than assigning an unmeasured value.

Common problems and next steps

• Screenshots from different resolutions can make spacing look larger or smaller; match the width of the mark first.
• Compressed JPEG images can add soft edges that make details appear changed; use the cleanest available source or compare only shapes that remain clear.
• A color picker value from a photo with mixed lighting may not match the official logo colors; it is a measurement of the image, not an official fact.
• If the image tool cannot export a comparison, take a screenshot of the two crops side by side without further editing.

Move on to a vector copy or a print-oriented file when you need to check exact spacing, outlines, or color codes. Pixel measurements alone are enough for a visual change summary, not for reproducing the logo.
