Opps, should have said that differently. I meant that "sierra tan" on many Buicks faded from the original so maybe your color did the same a little bit since the repaint. Goodluck finding the right color. :TU:
that color looks like my 69 riv that is olive beige. you might go to autocolorlibrary.com and check 68 and 69 colors. iverson
Don't let the chips fool you. They always appear darker than they should. That Riv is Buckskin. Probably a Delstar acrylic enamel.
