How to Make a Logo White, Black or Single-Colour (Transparent PNG)

When you need a white, black or one-colour logo

Most brand guidelines require at least colour, white and black versions. If yours does not exist yet, making them is one of the most useful ten-minute jobs in branding.

Step 1: Make sure the logo is transparent first

A recolour tool changes the colour of the logo pixels. If your file is a logo on a white rectangle, the rectangle is also pixels — recolour to white and you get a white rectangle; recolour to black and you get a black one. Remove the background first; our transparent background guide covers the process and the halo problem. A clean transparent PNG — or better, a vector — makes every version crisp.

Step 2: Recolour to solid white or black

1. Load the transparent PNG into the Logo Color Changer.
2. Choose White or Black and Apply to: Whole logo.
3. Turn Preserve shading & detail off. With it on, the tool keeps each pixel’s original lightness, which gives a greyscale image — useful for some effects, but not a true white or black logo. With it off, every visible pixel becomes exactly #FFFFFF or #000000 while the edge transparency (anti-aliasing) is kept, so curves stay smooth.
4. Switch the preview background to Dark when checking the white version — on the checkerboard or light preview, a white logo is nearly invisible and it is easy to miss problems.
5. Download the PNG, or use White + Black + Color (ZIP) to export the full set in one go.

Recolouring just one colour

Sometimes you do not want a fully white logo — only the dark text needs to become white so it reads on a dark header, while the coloured icon stays as it is. Use Apply to: One color only, pick the text colour from the logo, and set the match tolerance (the default 40 catches anti-aliased edges; raise it if a faint outline of the old colour remains). This is how many brands create their “dark mode” logo: coloured icon, white wordmark.

The multi-colour problem: when a one-colour version breaks

Converting a multi-colour logo to one colour merges every coloured area. That is fine when the parts are separated by space. It fails when parts overlap or touch and were only distinguishable by colour:

• A blue circle with a green leaf on top becomes one solid blob.
• Text sitting on a coloured shape disappears into the shape.
• Gradients flatten into a silhouette and lose their depth.
• Drop shadows become a thick, smudgy outline.

The professional fix is a knockout version: the inner shape is cut out of the outer one, so the background shows through where the colour change used to be. Tools cannot invent that — it is a small design job. If your logo falls into this category, ask your designer for “one-colour positive and reversed versions”; it is a standard deliverable.

White logos and dark mode

Dark mode is now common on phones, email apps and websites, and it creates a new problem: your full-colour logo may sit on dark grey without you choosing it. Where you control the code (your website), serve the white version in dark mode with a <picture> element and prefers-color-scheme, or use an SVG whose fill follows the text colour. Where you do not control it (social avatars, email), put the logo on a solid background tile so it never depends on the viewer’s theme — see our email signature guide for the email version of this problem.

Checking contrast

A white logo on a light-grey photo or a black logo on dark navy can be technically “reversed” and still unreadable. For logo-sized graphics, aim for a contrast ratio of at least 3:1 against the background (the level WCAG uses for meaningful graphics). Paste your logo colour and the background colour into the Contrast Checker. On photos, place the logo on the calmest area or add a subtle dark gradient behind it.

Naming and storing the versions

Keep all versions in the same folder with a predictable pattern: brand-horizontal-colour.png, brand-horizontal-white.png, brand-horizontal-black.png. The same applies to icon and stacked layouts. A full kit structure is in building a logo asset kit.

Print notes for black and one-colour logos

• “Rich black” vs pure black: printers often ask for 100% K (black ink only) for small logos to avoid colour fringing. A PNG exported as #000000 is fine for office printing; for professional print, send a vector PDF and tell the printer it is a one-colour K logo.
• Minimum line thickness: engraving, embroidery and small stamps cannot reproduce hairlines. Thin strokes may need thickening in the one-colour version.
• Resolution: for print, a PNG must have enough pixels for 300 per printed inch — a 5 cm wide logo needs about 590 px. A vector avoids the question entirely; see converting a PNG logo to SVG.
