EDIT: Prevent copy right/trademark infringement by not using company logo, but
<p>I want to prevent copy right infringement and therefore I don't use logos or fonts of companies on a site where I want to list them.</p>

<p>So it came to my mind to just use a standard open source font and mention the companies by name, but use their logo colors for the text and background.</p>

<p>I want to use the names (html+css) on my personal website to show a list of companies I have been working for on past projects. </p>

<p><strong>With this in mind, does it represent a trademark violation?</strong> </p>

<p><strong>For example:</strong></p>

<p><a href="https://i.stack.imgur.com/D7bA4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/D7bA4.png" alt="enter image description here"></a></p>

<p><strong>Would this be legal?</strong></p>

<p>There are quite a few misunderstandings in your question.</p>

<p>First, company logos and names are protected by <a href="https://en.wikipedia.org/wiki/Trademark" rel="nofollow noreferrer">trademark</a>, not <a href="https://en.wikipedia.org/wiki/Copyright" rel="nofollow noreferrer">copyright</a>.  The goals of trademark protections are very different from those of copyright, with the main purpose being to prevent confusion about the source of goods or services.</p>

<p>Second, using the name or logo of a company is <em>not</em> automatically a trademark violation.  You can freely use the name "Coca-Cola", or even the script logo, to refer to the company or its products, as long as you don't do so in a way that implies you are, represent, or have been endorsed by the Coca-Cola company.  The usual way to do that is with a disclaimer and acknowledgement of trademark ownership, but that's not strictly necessary.</p>

<p>Your idea of using the name and colors, but not the font, could actually be counterproductive: it could be seen as an attempt to circumvent trademark protections.  Either use the bare name in an ordinary typeface, or use the full logo, but don't go halfway.</p>
