It's a nice, simple game - I assume to help with teaching RGB hex codes to students?<p>Though now we have OKLAB/OKLCH - currently in Safari, hopefully coming to your local browser soon - I'm hoping the industry can start moving away from named color strings and RGB hex codes. I've always struggled to visualise colors from hex codes, and the named colors lie to me (why, darkgray? Just ... why?). Plus having a reliable color system will keep designers happy and a happy designer makes my front end day job easier.<p>I made a gradient game based on OKLCH colors. Sadly it lacks the addiction factor, but it was an interesting exercise - <a href="https://codepen.io/kaliedarik/full/YzvYadX" rel="nofollow">https://codepen.io/kaliedarik/full/YzvYadX</a>
