Of course, the appeal of any given color is subjective, but to my eye, a lot of these colors look great! Thanks @Stu_Barnes for posting all these images!
Just FYI comparing solid to metallic paint:
Solid paintThe vast majority of cars come with a ‘solid’ paint finish as standard. Most manufacturers offer only a limited selection of solid hues – typically white, red, blue and black. But even in that range, there’s usually a wide variety of shades to choose from. So, whether you want your car to disappear into the background or stand out from the crowd, you should be able to find an appropriate color without shelling out extra money.Solid finishes are free because they’re simple to produce. There are usually only three layers: primer, paint and lacquer. Many manufacturers now use a paint known as ‘two-pack’, which is simply the paint and lacquer mixed together.Repairing solid paint is easy: small stone chips can simply be filled in with a touch-up pen in the appropriate shade. Any car spares shop can supply the right pen for not much money. More significant repairs are comparatively easy, too, as the paint dries out quickly with the aid of a simple heat lamp. You could even do it at home, as the necessary equipment is inexpensive and an even finish is easy to achieve.You still need to be careful, though, to avoid the dreaded ‘orange peel’. This occurs when the layers separate, usually because moisture got in while they were being applied.They may not be the most interesting, but solid paint finishes are certainly the cheapest and easiest to look after.
Metallic finishesMetallic paints reflect light for a much brighter shine than solids. They come in a wider variety of colors and add relatively little to the cost of the car – from around $750 on small cars.The shine comes from a small amount of aluminum powder mixed into the paint. The metal particles pick up and reflect light, hence the shine. Multiple layers of paint and lacquer – which largely account for the extra cost – add to the effect.Metallics look their best under direct, natural light, but even on a dull day they still shine.Dirt shows more obviously on metallic finishes than solids, so you may end up cleaning your car more often. Be careful, though, as the paint marks more easily. Use a proper car shampoo – washing up liquid contains abrasive salts – and make sure there’s no grit on the sponge. Over-zealous polishing causes swirl marks and car wash brushes can leave marks, too. But any marks can usually be carefully buffed out.Metallic paint is more difficult to repair, as achieving an exact match is tricky. Even manufacturer-approved body shops don’t make any guarantees.They add cost and need more care, but metallic finishes add significantly to the visual appeal of a car and often boost its used value.
