We need to knowo what your exposure is.

Can we see photos?

I would stay with Sherwin Williams, Benjamin Moore and Behr.

You can start by googling popular pinks for low light rooms with X exposure and see what comes up.

Then you can reasearch undertones for that color and when they can appear. For example a gray paint color in my bathroom turns a sliight amythest at night. It is nice in this setting but you might not want it in a kitchen.

I like to stay with popular colors as they are tried and true are are favorites for a reason.

Paints wont make it that much lighter in there. You might want to invest in some lamps, both table models and floor models. Lighting is what makes it lighter.

Many paint chips with have the LRV on the back which is light reflectance value with (theoretically) pure black being 0 and pure white being 100. The black that is 100 is not really available in regular paint, and the whites that we use are not 100. For example, the white that I used in my LR is around 83. I also used a color in my house that has an LRV in the 9 range and it is Very Dark. I could actually feel the room getting darker as the paint was going up. And as I painted my basement from raw concrete block to a white LRV 83, I could feel it getting brighter. This all probably sounds pretty obvious but you might be surprised by some colors feeling like a bright color that actually absorb a fair amount of light instead of reflecting it, even if they are pink, or violet or green that look bright or pastel-like.

Tickled Pink has an LRV of 55 so it absorbs a fair amount of light even though it is a "bright color"

Violet Stone has an LRV of 29 so even though it is a cheerful color, it absorbs a lot of light and will make a dark room look darker

So whatever colors you introduce, the LRV will be a piece of information you want to use do determine how light that paint color will be (when reflecting a light source).
