Gmail icons in multiple colours are useful for multiple reasons, but if you use Fluid App to to create multiple independent Gmail “apps” for all your accounts, it is great to have different colours for each email by using Gmail icons.
Finding high quality app icons in multiple colours took some time, but here is the best result:
Find these icons: A preview was initially found at Flickr by the original author, but the site is down so the download file was unavailable. After looking at the Internet Archive of his site from many years ago, the zip file on his site was found to be named “gmailremix.zip”. Searching for this revealed a repository on Github that had all the files, allowing me to share the zip for easy access for all.
If you are after just the icon (.icns file) for each colour, here are the individual download links:
Gmail Icon Black.
Gmail Icon Blue.
Gmail Icon Green.
Gmail Icon Orange.
Gmail Icon Pink.
Gmail Icon Red.
