A metallic color shows the contures of the body more because of the different angles of the paint and angle the sun is reflected off of it. The lighter the color, the less curves you can see on a car. I have a white Fiero, and in the direct sunlight, you cant see the stock front fender flare, the little bumps in the hood/deckilid, and anything else, it is just all white. On my 86 Fiero, it is very dark metallic blue, with black bumpers, and I can see every curve in the sunlight. Yellow has a simmilar effect as white, since it is lighter, so would lime green, unless they have a metallic flake in it. But even then, the dark colors show more.
Also, the darker the color, the more reflections of the surroundings you get, so it looks shinier.
Here are my 2 Fiero's, and my dads 2-tone Fiero:

Notice, you can see more of the scenery on my dark Fiero, and therefore notice the lines, and curves more. In most of the pictures, all you can see of my whte Fiero is a big bright object. In these pics, my white fiero has hood vents and you cant even see them in any shots, the best one to see them on is the middle left, but all you can see is the hole.
Also to note, on the shot of all 3 at the rear (bottom right) you can see lots of scenery on my dark Fiero, none on my white one, and some on my dads red Fiero. You can see the little bulge above the rear fender on all but the white one. Yellow Fieros are inbetween the white and the red for showing lines. They show more lines and contures than the white color, but less than red.
And on my dark Fiero, you can see every spider crack, scratch, paint chip and everyting. Cant see any of it on my white Fiero, the roof has lots of hariline cracks in the clear coat on my white Fiero, but they are not visible untill you are 6 inches away. The front bumper on my white fiero has a big scratch that was touched up with a white color that is not close to factory white on the front tip of the passenger side. Also, the hood on my dark Fiero was touched up in the scratches with a different shade of dark blue.
