I'm using Benjamin Moore's Regal Eggshell paint (latex). One room is currently painted dark orange, the other lime green (both also with BJ latex paint), and I'm planning to repaint both of them to light cream. The third bedroom is standard white, and I"m planning to paint that one a soft, baby blue. All three rooms are small (110-160 sq. ft) with high, 9.5 foot ceilings, and don't get much natural light (especially the orange one).
My plan is to use primer tinted close to my topcoat, and follow that with only one coat of paint. The paint stores near my house charge an arm and a leg for paint and I'm on a tight budget, so I'm hoping this is doable.
My question is: Can I get away with using high-quality tinted primer plus just one coat of paint? I'm especially concerned if that's possible in the orange room.
I'm not looking to do a perfect job, just a decent one that I'll be happy with for the year or two I'm living there. Any advice/experience is much appreciated.
