Painting fun NOT

I have had problems with colors ever since grade school. I just never could make the colors go together. I tend to go with what others tell me or let them pick them out. That's how I got the wonderful yellow in my kitchen. Devonae picked it out for our house in Galesburg. So I chose it for the kitchen here.




I had no one to help me out on the rest of the walls. I was on my own. Not good. Off to Lowes and I picked a camel color thinking it would go well with the yellow. Got the paint home and found it was way to dark. Went back to lowes and they told me to add a quart of white to it.
So I added a quart of white to it. It made what I thought was a pretty color so I used it on the side wall next to kitchen and dining wall.








It doesn't quit go with it, but hey I got a custom color. I should have bought several gallons of the stuff because I had planned on doing all the walls with the tan color.
I didn't want to buy a gallon of paint and than have to mix a quart of white in it. I thought I could take in to Lowes and have them match it.








It would of worked except I took them the paint stick that had the original color I bought first. I told them that's the color I wanted only a little lighter. Got home and opened it and put it on wall. Its was really dark, so off to Lowes again. The paint lady hates me. She was nice, but I could tell she wanted to put me in the mixing machine and shake me up a bit.

Got home and put the paint on the wall. As I was applying it the paint was the exact color of the other wall. Something happened in the drying process. It got darker. I was afraid the lady at lowes really would put me in the mixer, so I just painted with the color I had. Now I have three colors on my walls. I need some help here people. I had planned on doing the hall the same color but its way to dark. But I hate to add another color to the picture.

What would be a good solution to this problem. Paint the hall a lighter color making four colors or stick with the same color and add more lighting in the hall. Would it be bad to go with another color. Should I just let the little lambs do their artwork in the hall?

This is the side wall on the other side of living room that goes into the hallway. I plan on using white for the trim.
