69 paint chips/touch up paint

I have seen paint chips for Rallye Green but have seen two different versions, one lighter than the other. The darker of the two seems to be more prevalent than the lighter color but I have the lighter color and am interested in getting some touch up paint. Does anyone have a source or any info on why the difference in the two shades of this color?

Not what you are looking for probably, but maybe of interest anyhow.

Many confuse 999 Rallye Green (darker) with F6 Bright Green Poly (lighter).
