Seventies huh? very light green was also a wall color along with the bright yellow. (my parents STILL have it

)
I like very light wall colors --- bone (a light white-beige) twilight blue (very light blue) and others, then I add color with the decorating. Paintings (you can tell what I like by the paintings I've used as avatars), tablecloths, pillows, and other little things bring in the color and I can easily change colors by changing these.
Good luck choosing colors. That's the fun part.
