Matching Touch Up Paint

[MRBXXXFVVS1]

I bought some paint to touch up a few spots on my walls. I got the same color, but the house was painted a few years ago. I unfortunately did not test it out and used it to touch up a few rooms, and it doesn't match. Does anyone have any advice on how to resolve this without repainting the entire house? Thanks!

So we just had our whole house painted in March and I wanted to match up the ceilings. I asked my painter to do touch ups but there were large areas where the nails popped out and the house settled. My daughter’s room had stars all over the ceiling too that we removed so her ceiling needed to be repainted. My painter had the local Sherwin Williams rep stop by our house and she did a quick tour and had one of the painters cut a piece of the ceiling out. I think it was a 2x2 square piece.
She took this with her and then he went and picked it up. It matches perfectly. In April I decided to do two walls in my bedroom over bc I didn’t like the original color I chose and I got some on the ceiling. I used the same ceiling touch up paint she had matched and it looks exactly the same as the rest of the ceiling.
I have a few paint chips on my painted kitchen cabinets and I found the color in the garage (Chantilly Lace by BM) but when I tried to paint over them the color came out too yellow. I’m planning to just take a small cabinet door with me to SW and have them match it up.

The door is a good idea, Hopefully they have a spectrometer ...not sure how something that big will fit - we used to like a big flake we would place on a white tile

Its not 100 % but tlid take as big as you can get flake of paint off the wall and the pain shop will put in under their spectrometer and get a pretty close match
Like a big flake - like a 50 c piece if you can

Matching exterior is trickier as even if they say they don't, paint still fades over time
i would recommend painting entire walls if its been a few years since you painted and definatly two coats over the chips

Do you have any of the paint left over. wet or dry? Or have the can with the actual label? Paint base forumlations change with time, and with lower VOC edicts and paint companies being bought and sold. There can be 3 or 4 different formulations for the same paint color name. It's possible that what you thought was "same" wasn't. Try to take in your actual paint somehow and have an actual paint store try to match it. Lowe's and Home Depot have switched to part-time low-paid employees, and the skill level, knowledge, and calibration of the machine (or lack thereof) can vary widely.

Unfortunately paint can vary enough that you can't touch up, even if it is the same color and same finish (flat,eggshell, etc).

If it were me, I would do what kayla suggested and cut out a piece of drywall to take to the paint store to color match. Then test the new paint on that piece of drywall to ensure it matches perfectly. If you can't get it to match perfectly, then you will have to repaint.
I've had to do this and in one room I taped the corner carefully and only painted the wall that had the mismatched touch up. You could not notice the slight color difference in the corner. But maybe your paint is too far off for this.
