I need to paint over some wall patches in my house. I have no idea what color or brand the paint is. I heard SW has a paint matching device, so I went into my local store to ask about it. The employee had no idea what I was talking about and just told me to go pick a color from the color wall or bring in a sample. I told him I don’t have a sample and would have to damage my wall to get one. He said, “Sorry, I can’t help you.” So I pulled up online where it talks about the color matching device. I asked if it’s something someone comes out to the house for or how that works, because I truly had no idea. He just looked at me like I was dumb and laughed while saying that sending people to your house is not something they do. So next to the register I see something that looks like it might be the device I had seen online. I asked if this is the color match device. He said, “Oh that? Yeah. Seventy bucks.” I asked if it can only match existing SW colors or if it can match any color for a unique formulation? He told me to look it up online because he didn’t know At this point I just did not have any faith in his ability to help me, so I didnt want to spend $70 if it wasn’t going to be able to match any color. So anyway, how can I get help with matching my paint?
