Sorry, I don&#x27;t have a Mac here to test, could you please file an issue here: <a href="https:&#x2F;&#x2F;github.com&#x2F;zserge&#x2F;palette" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;zserge&#x2F;palette</a> (yes, 0xrgb.com is open source).<p>By &quot;fails&quot; - you mean it doesn&#x27;t select&#x2F;highlight the color string, nor it does copy it to clipboard?
