<p>Mentioning <code>add-ons</code> on <a href="https://github.com/geany/geany/pull/2972" data-hovercard-type="pull_request" data-hovercard-url="/geany/geany/pull/2972/hovercard">geany/geany#2972</a> caused me to look at it, there is an option to make a coloured tooltip appear over some things that look like hex colour specs. (See what I mean by its a "catch all", its easy to miss things.) The capability is not CSS specific so it doesn't understand names or rgb() AFAICT but it may be sufficient for <a class="user-mention" data-hovercard-type="user" data-hovercard-url="/users/82d/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/82d">@82d</a> or somebody could improve it.</p>

<p>I beg your pardon for delaying the answer. there was a lot of work. the essence of the question is to display all the colors at once, and not when seeing. I want it to be like this <a href="https://github.com/ap/vim-css-color">plugin</a> does.</p>
