Familycar.com has pictures of the light blue (Pacific Blue) color, and I think it looks great. However, I have not seen it in person. It seems it may be easier to keep clean, and may be a bit cooler, than the other, darker blues...
I have not been able to see the "stratospheric mica" color in person or on the web; If someone has a picture of a 4runner in this color, please post the link here. Thanks.
