Most of the icons and brand colors on SimpleIcons have been derived from official sources. Using official sources helps ensure that the icons and colors in SimpleIcons accurately match the brand they represent. Thankfully, this is usually a simple process as organizations often provide brand guides and high quality versions of their logo for download.
Official high quality brand logos and brand colors can usually be found in the following locations:
1. About pages, Press pages, Media Kits, and Brand Guidelines.
1. Website headers (you can use [svg-grabber](https://chrome.google.com/webstore/detail/svg-grabber-get-all-the-s/ndakggdliegnegeclmfgodmgemdokdmg) for Chrome)
Working with an SVG version of the logo is best. In the absence of an SVG version, other vector filetypes may work as well (e.g. EPS, AI, PDF). In the absence of vector logos, a vector can be created from a high quality rasterized image, however this is much more labor intensive.
For color, the brand's primary color should be used. The official color of a brand is usually found in their brand guidelines, media kits, or some of the other locations mentioned above. If no official color can be identified, use the brand's primary web color or the most prominent color in the logo itself (please indicate why you choose the particular color in your pull request). Simple Icons stores brand colors in the standard 6 character hexadecimal format.
1. Scale the icon to fit the viewbox, while preserving the icon's original proportions. This means the icon should be touching at least two sides of the viewbox.
Make sure the icon is added in alphabetical order. If you're in doubt, you can always run `npm run our-lint` - this will tell you if any of the JSON data is in the wrong order.
The filename of the SVG should correspond to the `title` used in the JSON file mentioned above, and it should follow the rules below. If you're in doubt, you can always run `npm run get-filename -- Brand name` to get the correct filename.
1. Use **lowercase letters** without **whitespace**, for example:
```yml
title: Adobe Photoshop
filename: adobephotoshop.svg
```
1. Only use **latin** letters, for example:
```yml
title: Citroën
filename: citroen.svg
```
1. Replace the following symbols with their alias depending on their position in the title:
We use the source URL as a reference for the current SVG in our repository and as a jumping-off point to find updates if the logo changes. If you used one of the sources listed below, make sure to follow these guidelines. If you're unsure about the source URL you can open a Pull Request and ask for help from others.
If the SVG is sourced from:
- **Branding page**: For an SVG from a branding page the source URL should simply link to the branding page.
- **Company website**: If the SVG is found on the company website (but there is no branding page) the source URL should link to a common page, such as the home page or about page, that includes the source material.
- **GitHub**: For an SVG from a GitHub (GitLab, BitBucket, etc.) repository the source URL should link to the file that was used as source material. If the color comes from another file in the repository the URL should link to the repository itself.
In any case the commit hash should be part of the URL. On GitHub, you can get the correct URL by pressing <kbd>y</kbd> on the GitHub page you want to link to. You can get help at the [getting permanent links to files page](https://help.github.com/en/github/managing-files-in-a-repository/getting-permanent-links-to-files).
- **Wikipedia**: For an SVG from Wikipedia/Wikimedia the source URL should link to the logo file's page on the relevant site, and not the brand's Wikipedia pages. For example, [this is the link for AmericanExpress](https://commons.wikimedia.org/wiki/File:American_Express_logo.svg).
In general, make sure the URL does not contain any tracking identifiers.
We use [Semantic Versioning](https://semver.org/) in this project. Given a version number `MAJOR.MINOR.PATCH` you can expect the following kinds of changes:
