Some funky 70s gradients for you!
Schgain on X/Twitter asked for some retro palettes from the 60s, 70s, & 80s. Funny enough, I'm a history geek who watched a lot of TV & movies from this time period with my parents, so I know these well. :D
These palettes are based on clothes, art, & interior decoration of the 70s. There's not much organization, so feel free to reorganize/delete/rename things. These are color palette gradients: if you would like to use them as gradients that flow into each other, uncheck "[X] Mixing Rate Curve".

As an aside, the 70s had some great art & music, but my goodness, the interior design is so ugly. It's so painful to look at yet still somehow works. Dark Gold & Olive? Wall to wall carpets & wood paneling everywhere? Eugh. I'm so glad there were so many other fun colors they used.
