Well its getting hard to find those nice dark blueish/green...or would it be greenish/blue? Hmm...
Anyway, its getting hard to find them unless you buy a premium grade CD-R such as those straight from Taiyo Yuden's own brand (not rebranded) or Mitsui Chemical's.
I bought three 30-pack boxes of individually wrapped Maxell CD-R74 with jewel case about 2.5 years ago and I still have one box. They are substantially darker than the consumer level (inexpensive) Maxells, TDK, and Fuji you find today, even those made by TY.
I'm not saying they are necessarily lower quality. On the contrary, dye formulations have undoubtedly improved, and maybe they have improved in a way that the 'darker' hues are not necessarily indicative of higher quality. However, the Taiyo Yuden branded CD-R that come with a 50-year guarantee are noticably darker than those they produce for other companies, so that tends to make me think that darker is still 'better'.
