this is my design with a commonly used color combo Note: i use this with the plugin color changer,trust me it will look nicer

                  Blue team: Body color pink, decal Dissolver, wheels Roulette pink, boost Sparkles sky blue

                  Orange team: Body color sky blue, decal Dissolver, wheels Roulette sky blue, boost Flamethrower pink

                                            it looks nice on every car imo
