i saw it on a CL ad and it said it was the original paint, the name of it is Flamboyant Lime and its from 74. Has anyone seen one this color in person?
According to a quick Google search, Flamboyant Lime is a Schwinn color and seems to have been used on some of the earliest stingrays in 63. Whether or not they used it on 74 suburbans is beyond the time I want to spend Googling Although, just from the pictures I just saw of other Schwinn's in that color, this one looks more "flamboyant", so as already mentioned, the photo may have been altered to "gay it up", a bit.
That'll have to be a Suburban, because it has a chainguard. The varsity sport also came in lime in 1974 but it didn't have the full chainguard. The color was called lime, no mention of flamboyant. I looked through the other models, only these two I mentioned came in lime.
The photo in the ad must have been enhanced, the lime isn't anyhwere near that flamboyant. This is from the 74 catalog:
