Pantone 448 C
&gt; Pantone 448 C, also known as the &quot;The ugliest colour in the world&quot;, is a colour in the Pantone colour system. Described as a &quot;drab dark brown&quot;<p>Things leading the ratings of the ugliest things are rarely ugly. This applies to architecture and it seems to be the same with colors.<p>Dark brown is not the ugliest color, the ugliest color is magenta. It is commonly used as a transparency placeholder for a reason - nobody wants to actually see it. Just imagine a website with #4A412A background - it&#x27;s ok, people will read it if you put something interesting there as soon as you use a reasonable color for the font. Now imagine a website with #FF00FF background - it&#x27;s a disaster, everybody is going to close it immediately as soon as they accidentally navigate to it, no matter what font color you use.
