I’m working on a new logo for my site and ran into a weird issue. The logo background and the page background have the exact same hex code (#3A6EA5), but when I view the site in different browsers, they appear as different shades. I saved the logo as a PNG-24 to avoid GIF’s palette limitations, but it’s still happening.

I’ve tested in Chrome, Firefox, and Safari, and there’s variation across all of them. I’ve read about gamma correction issues in old browsers like IE7, but I thought modern browsers solved that. What’s causing this? Is it a color profile problem? My design software (Figma) exports with sRGB, but maybe the PNG is missing the embedded profile?

Any tips for ensuring consistent color display across browsers? I want both the inline CSS background and the image background to match perfectly.

Great question! Gamma correction isn’t the only culprit here. Modern browsers still handle color management differently. Chrome and Firefox use the system’s color profile, while Safari applies its own. The key is to ensure your PNG has an embedded sRGB color profile. Many design tools strip it by default, so check your export settings.

Another approach is to avoid relying on the image’s background entirely. Use CSS to set the background color on the element, then place the logo (with a transparent background) on top. That way, both the logo and the surrounding area use the same CSS color value.

For logos, consider using SVG instead of PNG. SVGs are resolution-independent and can inherit colors from CSS, so you can define the logo color via a CSS variable like --logo-color: #3A6EA5;. This eliminates color mismatches entirely. Plus, SVGs are lighter and scale perfectly.

Testing with your browser’s developer tools is also essential. The color picker in Chrome DevTools can compare actual rendered colors. Use the eyedropper to confirm the displayed values match your intent.

Finally, if you’re still seeing minor variations, you can force color management in CSS by setting color-interpolation-filters: sRGB on the image element (though support is limited). In most cases, properly embedding the sRGB profile and using a consistent color space in your design workflow solves the issue.
