Car is in color!!!!!!!!!!!!!

Did you use a hardener in your clear coat ? and I think the air pressure you used though you gun was a bit low and it could be the brand clear and reducer you used.
What temperature reducer did you use ? and what was the temp when you painted it ?
Adding hardener to your last two coats always seemed to lay down better and is a must do.
How many coats of clear did you get put on will help a tech with what you need to do.
I have been there before and water sanded with 800 with two paint paddles "stir sticks" and put water in a spray bottle and sanded till it was flat, sand an area and use a new un used bondo spreader or squeegee to wipe dry to see if it is flat.
Look at your clear coat can and see how long you need to wait before doing any sanding, I do know the sooner you do it the easier it will sand, just don't do it to early!! you will see it building up on your sand paper and make scratches in your clear coat, so keep your sand paper clean and wrap some 800 around a paint paddle and keep turning the paddle to keep fresh paper on the side you are using.
A good paint tech will jump in here soon to help you along and may say to use different grain sand paper. So sorry to hear the bad news this morning for you, but it does happen to the best of them . You did say it's the wrong color,
