Filter list with Linq

I have a class :

public class Car
{
    public string Color { get; set; }

        public string Speed { get; set; }
}

And one instance :

List<Car> Cars = new List<Car>()
{
     new Car()
     {
           Color = "Green".
           Speed = "100"
      }, 
      new Car()
     {
           Color = "Yellow".
           Speed = "150"
      }
}

I want to filter this List

I do :

List<Car> Conditions = new List<Car>()
{
     new Car()
     {
           Color = "Green".
           Speed = "100"
     }, 
     new Car()
     {
           Color = "Yellow".
           Speed = "100"
     }, 
     .......
}

How to browse my list and take only the car which corresponds at least to a condition with Linq?

Here, take only the first index of my list for example
