New Calendar Colors!Clicking on that link brought me to:
Google Calendar has a new palette of 24 calendar colors to go with our new look. Check 'em out!
We're sorry, but the information you've requested cannot be found. Please try searching or browsing the Help Center.*eyeroll*
Also, there may be more color options for individual calendars (it's been a while since I added a new calendar, so I can't remember how many color options there were), but there's still only a half a dozen (albeit a slightly different half a dozen than before -- which seem to be all kinda pastely, which I'm not such a fan of) for differentiating events within my own calendar. (Though possibly they have reinstated the borders on my individual events -- plus calendars-not-your-own now have subtle cross-hatching, which also helps distinguish them from my own calendar items)
