Why are you not sure, is it dark?
It is to close to white and the trim, door & railings are also white. It's not looking the why I had hoped for.
I take it that you want it darker? Call whoever you got it from and see if they'll add color even tho you've already used some. If not, you can buy color additive and mix it yourself - little at a time and stir good.
The paint manufacturers' web sites have apps where you can pick colors, apply to the walls, woodwork and ceilings to see how you like the look.
Kathleen, I like Evelyn's advice. You can use the Sherwin William's Color Snap app, I just recently used it myself and it really helps you visualize what you're doing. You can even post the picture here and ask for more feedback before you repaint. Do you have a picture of what it looks like now?
With this tiny bit of info, I feel like you need some color. However, when using light trim & walls, it will always look better with pictures, furniture and accessories.
