Flat Logo Redesign: How to Evaluate the Before and After
A practical guide to reviewing a flat logo redesign before and after the change. Learn what to compare, how to check contrast and scaling, and which output variations to prepare.
Before you start
A flat logo redesign usually replaces gradients, shadows, outlines or detailed illustration with simpler shapes, limited color and clearer edges. The goal is not to remove personality, but to make the mark easier to recognize at small sizes, on different backgrounds and across digital screens. For this review you need the before and after logo files in a lossless format such as PNG with transparency or SVG, plus the original brand colors and the smallest common placement size.
The evaluation should happen locally on your device. If you are using a browser-based tool, check whether the tool explicitly says that the selected files stay on the device. Do not assume a local preview is private unless the interface states it. For this procedure, keep copies of both the original and redesigned files so the comparison is reversible.
Step-by-step instructions
Place the flat redesign next to the previous logo at the same visual size. If one version has a wordmark and the other does not, compare the marks separately and then compare the full lockups.
- Check silhouette first: lightly blur the artwork or step far away from the screen. The redesigned mark should still read as an intentional shape.
- Reduce difficult details: look for thin strokes, small gaps, overlapping shapes or close colors that disappear at thumbnail size.
- Count the colors: record the palette in the new file and compare it with the old palette. A useful flat redesign tends to remove near-duplicate tones rather than adding them.
- Test at the smallest planned size: if a favicon or social avatar is required, compare both files at 16 and 32 px. Choose the design that keeps the central idea legible.
- Switch backgrounds: place both logos on light, dark and mid-tone flat fields. The after version should have a defined boundary or a planned transparent variant for each intended background.
- Compare contrast, not brightness alone: two colors can look different on screen but still fail as a text or mark pair. Use a contrast checker on the main color combinations from the new palette.
- Review the shapes: zoom in to check that curves are smooth, corners look deliberate and parallel edges remain parallel. In an SVG, this can also reveal unnecessary points or irregular geometry.
If the redesign came from a template or is stored in a new file format, confirm that the intended colors and transparency are carried through. For example, an SVG that displays a white mark on a dark preview may still need a separate light-background color check.
Check the output
A successful before and after review should end with clear notes on what improved, what was lost and what remains unchanged. The after logo should keep the core idea recognizable on a plain background and at a small size without extra effects doing the work.
- Recognizability: the main shape or letterform still identifies the same subject.
- Legibility: small text, key details and gaps are still visible at the minimum intended size.
- Contrast: main color pairs meet at least the basic legibility markings in the checker.
- Shape quality: edges and curves are clean when viewed at a large zoom level.
- Version coverage: light, dark and transparent variants exist where the placement requires them.
For a fair result, do not judge only by the largest presentation. A flat logo can look simple on a hero banner but fail in a small interface context. The final check is the smallest real placement, not the most impressive one.
Common problems and next steps
A common issue is overcorrection: details are removed so aggressively that the mark becomes generic. If the redesigned icon could belong to several unrelated companies, restore one distinctive element rather than adding back shadows or gradients.
- Small details vanish: simplify a complex shape instead of repeatedly increasing its size.
- Transparent logo disappears on dark mode: create a separate light variant or place it inside a fixed brand surface.
- Colors look flat but muddy: reduce the palette further and replace near-identical hues with clearly separated tones.
- SVG preview matches but PNG does not: check the exported resolution, text-to-path conversion and embedded transparency.
- Wordmark lost its character: compare type choices independently from the icon changes, then reconsider the combination.
- Contrast checker reports a fail: test the pair with a larger mark and with reversed colors before accepting the palette.
After corrections, export tidy variants with consistent names and sizes. Keep the original file intact and store the revised set separately so any later change can be compared in the same way.
