The Jeeps stand in a perfect line, ready for an adventure. The two smaller Jeeps in the front have their headlights shining brightly, as if excited for the journey ahead. In the back, the bigger Jeep is ready to make sure everyone stays safe. Though their colors are the same, there is still a bit of personality to each Jeep, as if they've been on countless adventures and journeys. To bring this image to life, I would give the Jeeps a little bit of personality to make them stand out. I would use warmer tones for the two smaller Jeeps, like a golden yellow and a light brown, giving them a bit of a vintage feel. For the bigger Jeep I would go for a more modern style and use a bright green and highlight it with neon oranges or blues.
