Hubs is/was a painting contractor for over 30 years. Residential only. I am clearly color impaired since he can see colors with backgrounds and shades, like your wife, but I can't. Looks gray to me. Looks blue to me. Looks taupe to me.
One thing that he does is do half or quarter formula on adjacent walls. And always paint the ceilings lighter - they show up darker, but its an illusion.
What the heck is with the window instead of a slider? Thats just crazy. Go scour HD and Lowes for clearance windows. Once the MST's come thru (outside company hired by the big box stores) and mark down products by department, to make room for incoming product, that is when you'll find good deals. Oh, and the crew of MST's goes from store to store. So the store in Channing will have this dept marked down, but store #3 in Cleveland won't yet, cus the MST's for hardware/building haven't gotten there....I learned alot by talking to my local manager cus we have two HD's and two Lowes.
Another thing I thought of the other day: if you don't already, go get a Exec membership at Costco. Open a Citi bank Costco CC. Then buy your new appliances (if you go new vs used) and you get double rebate on both the citi card and Costco. This adds up for major purchases. Then when you're done, cancel your exec membership. This was explained to me by a Costco membership person.
