Clipped screenshot taken from the website mentioned below (provided externally there by <a rel="nofollow" class="external free" href="https://cookielaw.org">https://cookielaw.org</a>) illustrating the use of a dark pattern to trick users into consenting to the placement of cookies, in this case the consent button emphasized with colour, the settings button that allows for customisation using an inexpressive potentially misleading label (translating as "list purposes"), while a button to directly dissallow the placement of cookies is hidden by low-contrast writing and placement in the upper right corner, separated by placement and design from the other choices.
