Hi, I have red-green color blindness genetically. In fact [1], 7-10% of human population has the same problem. It makes us hardly distinguish the "existing" and "non-existing" links in DokuWiki, because their default colors are green and red.
To improve accessibility, I hope DokuWiki team would consider to change the "existing" link color for the default DokuWiki installation. For example, using a blue color for "existing" link is quite visually understandable by a web browser user.
Thanks in advance.
