Maybe the issue is the light bulb itself. Unfortunately, due to recent government mandates, you can no longer buy a true 100 Watt bulb. Many of the bulbs now claim to be "100 Watt equivalent" but really are not. Example: Those 72 Watt halogen bulbs give off 1450 lumens of light. Just before these began appearing on store shelves, a good 100 Watt 750 hour lifespan bulb gave off 1690 lumens. But it's worse than that because of how lumens are measured. The new halogen bulbs give off a slightly higher color temperature (not a bad thing in itself) that inflates the lumen value. In other words, the light from the old incandescent bulbs in actual practice felt "more full" and provided better illumination than it's lumen rating alone would suggest. Another example: There are special bulbs labeled 'rough service 100 Watt'. But the rated Wattage here is only theoretical because these bulbs would only actually be 100 Watts when operated on 130 volts. The voltage that comes out of your wall socket is 120 volts. That means that in reality the bulb consumes 88 Watts, and because the filament is glowing at lower temperature, it only gives off as much light as a regular 75 Watt bulb. Many people may be inadvertently using these rough service bulbs and have no idea why it is giving off less light. Then there are those twisty spiral compact fluorescent bulbs (CFLs). These things can often take 20-40 seconds to fully warm up, when you first turn it on it will only be at about 40% of its rated light output. But there's more. CFLs generally put out less and less light as they get older. A really cheap CFL can lose 30% of its light output after about 2 years of ordinary use. This forces many people to have to use a higher wattage than what they supposedly need. The law bans any Wattage higher than 72 Watts and less than 150, but is designed to automatically ban the 150 Watt bulb too if people buy too many of them. The idea was to try to force people to use less energy.

I wasn’t able to edit my comment to add my answer to your question. I have a ceiling fan with awful lighting that I don’t use, and two table lamps. I want to get a leather chair for the corner next to the fireplace so I can set up a standing lamp next to it. In the future, I really want to install recessed lighting.

I don't think the issue is the color, I think it's the lighting. What is the material used for the ceiling? Is it dry wall over concrete or is it drywall over wood? If the latter, I'd consider adding recessed lighting to brighten the space. Put them on dimmers so you can adjust as necessary.

I would start with changing the light bulbs to 5000k Step 2 is to get a few samples of paint color to test. I like to paint my samples on 140 lb watercolor paper - heavy enough that it doesn't warp and pretty inexpensive. 30 sheets for $7.00 https://www.amazon.com/Canson-Watercolor-Textured-Charcoal-100510941/dp/B004M59O4C/ref=sr_1_6?dchild=1&keywords=watercolor+paper&qid=1591914621&sr=8-6 To see what the color really looks like you may need to put some primer over the yellow paint, but since you are going to paint your going to need to prime anyway. Paint 2 coats of your sample colors on the watercolor paper. Set it on the counter against the backsplash and see what it looks like. Then set it nest to your sample of sofa fabric - how does it work with the fabric. Then look at it next to your trim and then sitting against the wall next to your flooring. This will need to work with all these different surfaces and colors. Seeing your space the first color I would try is SW Creamy. It has a hint of yellow, but not anything like what you have. If you go too gray it will fight with the gold in the counters, if you go too yellow it screams yellow. The goal is to find that perfect balance of gray and yellow. Here are some visuals of SW Creamy, BM White Dove (super popular right now) and BM Pale Oak (recommended by CDR Design). There is no way to know exactly how each will look in your space - as I said, computers are not a really good way to see colors, but given this is the only way we have to share here is what I am seeing. Once you have tested one or two or three colors you can let us know what you like or don't like about each color, share some pics and we can help you refine the color.
