Not quite. They don't really have a fully black SG - maybe someday, people have requested... Black Pearl is more rather dark silvery grey.

Not sure how thorough you wanna be, but there are several different yellows, different reds, different pinks, different oranges, etc. Lighter and darker hues, opaque and transparent ones, and so on. Like your green ones there - obviously not similar colours at all. Gotta warn you it may get pricey - but it'll look great. ;)

If you want lighter yellow between your Celebrate and Calacas maybe add Happy Hippy (transparent) or Yuzu and Cocoa (opaque). For other yellows besides Calacas when you need replacements later on I'd recommend trying Back For Breakfast (related to Calacas).

I can't tell if your Karma is red or orange - looks red to me there, but mine is orange. Either way, for pretty opaque orange I'dd add Uluru, for bright orange Bubbly - or for less bright but transparent one Ponche. For red Aura Suavis (opaque) and Two Hearts Beating... (bright), for very dark red Hot Toddy or Glögg. For pink Snow Fairy. And then there's Ginger to add to hues of red - a pretty, pale one.

I can't in good conscience recommend Yummy Mummy since I hated it, but it's one of the prettiest ones for sure. Many do love it, though, and I suppose if you don't, you could just... admire the pretty colour. :)

Looks like you need blue. Prince or Narcotick? Or Dirty or Freeze maybe if you're into those type of scents more. Or Ol Blue Skies, but like you said... well, there's always the next time.

And so on. Good luck with your rainbow - and bank account, ehem.
