I agree with JHs. If there is no new color on it at all, just talk to the painter about it, if it was an honest mistake (which can happen very easily while painting) your painter should have no problem fixing it. However, in my years of experience, it is not unusual for 2 coats of door paint (good quality) not to cover very well at all. I once painted a red door 7 times, plus a tinted prime coat before I found the door to be a solid color.
Not only do I agree with what you are saying; but, I will not use Angie's List for referrals again. Their "A" rated painter did some of the exact things they are now warning against; however, they are still rated "A". I sent in a review and it took eight weeks to post it. They allowed the contractor to lie about what happened as a response. I had proof and photos. Angie's List is a scam; instead ask neighbors and friends for referrals!
Beginning with the prep work and ending with last coat of paint or the finishing, an exterior paint job will last anywhere from one to two weeks. After completion, homeowners using low-quality paint will need to repaint every four or five years to keep it well maintained; homeowners using high-quality paint can go longer without a new coat -- usually about seven or eight years, depending on the type of paint and material.

Painting professionals might charge more or less to paint your home's exterior based on its construction material. Some materials cost more to paint than others because of their texture, the paint required to properly cover them, and whether specialized materials are required to prepare them for painting or the elements. Find more information on the various types of siding available, as well as how much it might cost to paint or prepare each.

When the primer is dry, caulk all small joints (less than ¼-inch-wide) in the siding and trim. Most pros use siliconized acrylics—paint won't stick to straight silicones—but Guertin and O'Neil like the new, more expensive urethane acrylics for their greater flexibility and longevity. O'Neil stresses that it's shortsighted to skimp on caulk. "If the joint fails, you're back to square one." Guertin uses the lifetime rating as his quality guide. "I don't expect 35-year caulk will last 35 years, but it should last longer than a 15-year caulk."
A thorough scrubbing is a must before painting any exterior surface. It removes the dirt and broken-down paint residues that keep fresh coats from adhering and gets rid of mildew that grows on paint in all but the most arid climates. Most contractors clean with pressure washers, but in the hands of someone unfamiliar with the equipment, these can gouge wood, shatter glass, and drive water behind siding and trim. Using a hose, a pump sprayer, and a scrub brush is slower but safer, and just as effective.
