Problems with drywall texture flashing

My house has a light knock-down texture. When the drywall contractor completed finishing, he primed the flat walls before he textured. This was to minimize the difference between the paper and the joint finish areas. After the texture was applied, I waited 5 days for everything to dry and I sprayed first coat of drywall primer with my airless. Next I sprayed the ceilings white. The walls were then cut in and rolled with another color. Now when I sight down the walls in the light, you can see the differences in the walls. I’m told that this is called flash. The problem is bad enough in the hallways and in my bedroom that I want to repaint it. What should I do to eliminate this problem and get a consistent finish? Thanks ahead of time for your reply.

My guess is the texture of the dw paper and the mud joint are different.
If that's the case a light sanding of your walls may help to even it out.
You may have to use a high build primer before you sand to get it right. Be careful with the primer, some of it is really hard to sand if you get runs drips or sags. A light coat should work.
Did you also notice "flash" around the top of the wall from the ceiling primer overspray?
The higher sheen of the finish wall the more you will notice differences in surface texture.
Good luck getting a finish your happy with,

You sprayed enamel on the walls with out vinyal primer base coat.
Painter before you sprayed his finish.
Wall were never rolled with primer or sprayed with high build .
Roll a heavy coat with a 1 1/2 inch lambs woll roller and back roll . Get all you can get on in one coat or two light coats. Then roll the enamel.

Had a the same thing happen on a spec to the point I knew it would not sell the way it looked. My painter re-primed everything and re-painted still had the problem. Checked with another painting sub and he sprayed everything with a gloss paint, then primed and then painted. It took three coats to make it look good but it took care of the problem. Painter told me he has had that problem before and that was the only way he knew to fix it.
People tend to see such things, try some funky way to fix it and like majic it goes away. Most times it's just not enough paint on the walls, especially when the operator is using an airless.
Right from Sherwin Williams is the following on some causes of flashing:
• Heavy dew, moisture, or condensation getting onto a coating (e.g. primer, paint or stain) while drying.
• Temperature fluctuations during drying.
• Coating over a porous surface.
• Paint applied at uneven film thickness (i.e. lapping).
• Insufficient film build (e.g. coating applied too thin).
