Why were the 90's literally so blue?

Literally! Lol, just think about it. Particularly the late 90's, especially 1998-1999.

For one thing, every expansion team in the 90's had to attempt to shoehorn blue/teal or purple into their team colors. For example: the San Jose Sharks, Florida Marlins (which at least actually fits into the local flavor or Miami), Jacksonville Jaguars, etc.

Secondly, the color blue was just about everywhere in 90's music as well. Eiffel 65 had a whole song about it ("I'm Blue (Da Ba Dee)"), and the color was overwhelmingly incorporated in a ****-ton of music videos throughout the decade. Three of the four music videos for Madonna's 1998 album, Ray of Light, were immersed in blue (the title track, "Frozen", and "The Power of Goodbye"). "Black Hole Sun" by Soundgarden had a blue sky set as the background for most of the video. Metallica's "Enter Sandman" was another video that was covered in blue. The video for "Come as You Are" by Nirvana was another one. TLC's "Waterfalls", The Verve's "Bitter Sweet Symphonie", "I Want It That Way" by the Backstreet Boys, Enimem's "My Name Is", "Doo Wop (That Thing)" by Lauryn Hill, "Are You That Somebody" by Aaliyah, "I Want You Back" by Mel B and Missy Elliot, "Ava Adore" by the Smashing Pumpkins, "Say It" by Voices of Theory, "If You Tolerate This Your Children Will be Next" by Manic Street Preachers, "Californication" by Red Hot Chili Peppers. Even lesser known artists such as Hooverphonic had it EVERYWHERE in their videos, like "Eden" (which had a popular cover by Sarah Brightman), and "Inhaler". Even their first three albums all had blue artwork.

Anyways, the list goes on and on. Even look them all up if you are curious.

Is it just me or have y'all noticed this too? Why were the late 90's obsessed with blue/teal?
