Epic #89595: Improve accessibility of backend
Button "Show all" in search dialog modal has insufficient color contrast
When you type text in the search input field and the search modal dialog appears with multiple results, there is a button at the end which says "Show all". This button has insufficient color contrast of 2.7 (foreground color: #ABD0F0, background color: #0078E5), see WebAIM Color Contrast Checker.
<a href="#" class="btn btn-primary pull-right t3js-live-search-show-all">Show All</a>
To fix this issue, increase the contrast to a contrast ratio of minimum 4.5:1.
