The previous entry (Josef Eines / alarmsystem.no) returns a connection error — the domain is no longer active. Replaced with a working WCAG color contrast checker and moved it to the correct alphabetical position within the category (between "We are Colorblind" and "Who Can Use").

Hey @reallymello, I have found some links that we could update rather than simply remove. I'm going to make another PR for the same issue. #1647 |

Summary
Removes a dead link to
https://www.alarmsystem.no/color-contrast/which returns a 404. The domain (alarmsystem.no) is a parked domain, appears unrelated to accessibility tooling, and the entry looks like it may have been spam.Replaced with WCAG Color Contrast Checker, an actively maintained tool that includes colorblindness simulation for four deficiency types (deuteranopia, protanopia, tritanopia, achromatopsia), accessible color variant suggestions, and a markdown bug report for logging accessibility defects.
