We are wanting to paint the side on our house but leave the brick as is for economical reasons. I am stumped on what colors to choose that will also compliment the brown brick and roof. I am wanting to do a darker siding color and a light trim color. Any suggestions would be greatly appreciate!!

No ideas without you posting pictures of the house. You cannot just describe colors and expect people to provide you with a solution.

Re ”old house” in an impressive way or that its dated looking? IMHO "dated" vs "not dated" doesnt apply once a house gets to be a certain age. The esthetic question should be more like - is the updated color scheme in sync with the historic style of the house? Is the color placement correct - that is as important as which particular colors. For those reasons the blue gray with white trim pictured above I consider an example of what NOT to do - mostly cos the white trim /dark body while very attractive on a 1920s style cottage (for example) doesnt work so well for this particular style of house. Gives it a barn-like look. Im not sure where you are - guessing US since youre using SW, but kinda looks like Euro version of a country house and stucco traditionally would be a traditional limewash or silicate based mineral paint color.... with dark trim. Google images for limewash colors. That said - a soft whitewash color for the body of your house certainly would be very appropriate. Ticks both boxes - historic/architecturally appropriate, AND a current favorite! What kind of paint is currently on the house? If its never been painted with modern housepaint I strongly suggest you use a mineral based paint instead of modern acrylic based paints. Besides Romabio (hey where are all the Romabio people when you need them LOL) other US companies who can help are limeworks.us and beeckmineralpaints.com, both with excellent customer service and they can custom mix to match any paint co color. I found the cost to be quite comparable to good quality housepaint.

If you live in or near a city, sometimes the flagship stores of the major brands have color consultants in house. They will give you advice for a nominal fee. Also, six months ago we got quotes for interior painting and the two largest companies had in house color consultants. No matter what you do, sampling is the most important part of the process. It's difficult to extrapolate from tiny paint chips to large exterior wall surfaces. You need to paint large sample boards, look at them on propped up on all four walls of your house at different times of the day and on sunny and cloudy days. If you are having trouble deciding, update your post or start a new one with pictures showing your house and the sample boards. Only you know what you like so try to get down to a couple choices before asking others for their input. You also want to figure out whether you like light, medium or dark tones. I recommend starting with Ben Moore's Historical colors, they're almost all great for exteriors. If you prefer SW, they also have a Historical collection. If you already know who the painting contractor is, ask them what their preferred brand is so you don't waste your time looking at the wrong brand's selections. If you can choose a body color, the commenters here can help with trim colors if that is stumping you. You will need to post a picture of your house so we can see your roof color and how much area the trim takes up, etc.
