You have to look for the tool polygonal lasso clicking the lasso tool with the right click and zoom a little bit pushing the button alt+scrolling up with the mouse, ( you can use magnetic lasso to make it faster but i'd rather using polygonal lasso, make it more perfect) im going to start selecting the car

1. Click the adjustment panel and click hue/ saturation and you will see this
