The problem with lightening a color after mixing is that the lightening will be approximate unless measured carefully and you have then created a custom color. It's better to get the paint store to customize because they'll put the formula on the can so you can replicate it with 100% accuracy. If you like it you may want to use it in other rooms, or may need to buy more later for touchups. I have EG in my master bedroom and Pale Oak in my living room. It's interesting you say Pale Oak looks a little pink. I have heard someone else say that but it never looks at all pink in my room which has a strong southern exposure. So maybe it's the lighting under certain conditions. In my experience, lightening a color by 25% doesn't make a noticeable difference. But a lot of the time if you go to 50% you should be choosing a different color. Have you looked at Ballet White? This is a popular color along the lines of what you're looking at, but lighter. Or maybe you would like Classic Gray? It depends on how much gray you want and how light you want to go. If you already have bought a can of EG, try painting a large section of wall with it to see if you like it better or worse once you see a lot of it. If you are painting over a lighter color it might look dark next to it, but look good once you're not distracted by the old color.

I am not a fan of Edgecomb. We used it in a rental property and it looks murky.

I agree with Kendra. There are many “ whites” that would work.

I just used BM Elmira white for my kitchen refresh.

Eld6161 can you post some pics of your kitchen? I would appreciate seeing elmira white up. I am also in the midst of choosing a white.

Lighting impacts any color but EG is a VERY chameleon color...more so than many. It could also look very different on each of your walls within the same room. I have it in a guest room now where it reads a light gray (I don't like it) but in my Colorado windowless powder room it was a very warm beige. I wouldn't use it as a whole house color because of the extremely different appearances it might have.

Pale Oak also had pinky undertones in my home. Are you going for a true gray? Are there any colors of carpet, furn etc that you are taking into consideration? It's easier to start with upholstery or rugs sometimes as it's easy to then pick a paint that complements them. Not so much vice versa.

It's a great color. Easy to live with and not that dark. Use it as is.

I tried Edgecomb gray in my previous house and it was a bit drab/cold in my rooms. I ended up using BM Grant Beige.

It's a creamy light beige.

Edgecomb Gray is a lovely greige, but if the natural light (North) or your light bulbs are giving off a mean light, that could be the reason. Cutting it isn't going to change it. You are still working with the same undertone (green).

Try B.M. Collingwood. My opinion, it is the very perfect whole house wall color as it works well with all exposures.

@eld6161, it looks pretty good in the space. Actually looks much warmer than mine did.

Its looks great. it looked too warm at my house with my finishes. your granite really pulls it together.
