Ron,
That will take some practice. I would practice on a piece of scrap and paint it all red and then start at the other end and paint it black.
As you come to the part that you want the color to fade you will have to learn to pull the airbrush back further from the surface to get an even softer line. You also need to get the feel of pulling back the airbrush trigger really softly so that the paint coming out is so light that you would need to hold it in one place a while to get the color to build up.
If you learn to pull back away toward the part you want feathered, along with learning to push the trigger forward as you move the airbrush, you will get a real soft fade. It is going to take practice though.

Just remember to always hold the trigger down all the way and learn to educate your index finger as to how to move that trigger to get the amount of paint you want for the effect desired.

“Wisdom is the right use of knowledge. To know is not

for it. There is no fool so great a fool as a knowing fool. But to know
how to use knowledge is to have wisdom. " Charles Spurgeon
