Here is another one with a dark gray (soft black) like you suggested originally. Two views shown below. ^ The trim is F&B "Railings" color. F&B refer to it as a soft black http://us.farrow-ball.com/railings/paint-colours/farrow-ball/fcp-product/100031

You haven’t said anything about budget. Change out the siding color starting from the colors in your brick. I would want something somewhat darker than the current color. I can’t see that adding cedar shingles to the top part of the gable ends, leaving the rest as it currently is, will be an improvement. Changing out the garage door for one with windows is a good idea. Match its color to the siding as the white highlights something that doesn’t need extra attention. Widen the walkway so that two people can walk abreast, and make it of more interesting material. Find a garden designer to help you come up with a garden design that suits both your taste and ability/interest in doing the needed maintenance. What you currently have has some evergreens which is good, but there isn’t anything interesting or that complements the architecture. You landscape is stuck in the 60’s with nothing except for your two rows of evergreens and a small patch of some type of flowers.

Thanks for the Alabaster suggestion... we just painted the cabinets Alabaster, and have it as (most) of our trim. It's gorgeous... but very unfortunately, too light for our exterior. The Austin Stone in the front of the house is pretty bossy, and really seems to need 'more' when it comes to color. I love Alabaster... it just washes out in our east-facing entry.

I copied and expanded a piece of your brick, and you can see the pink in it. So your brick is a pink-beige. Sometimes described as beige with red undertones. That's why the yellowish siding doesn't look quite right, and IMO the copper, although very beautiful on its own, doesn't complement the brick. (If you had a sweater the colour of your brick, you wouldn't wear it with an orange/copper shirt, I hope.) Here's an article about working with pink-beige. It's an easy colour to go wrong with. The article talks about interiors but the advice would also apply when you were looking for a siding colour, for example. I wouldn't use sage green with it - the example shown above is a very popular one, often re-posted. The orange brick looks great with sage green. But orange brick is not what you have. I am a fan of almost any brick colour and I'm from Toronto where everything is brick and nobody paints it. But if this were my house I would paint it. Use a coating meant for brick such as Romabio, not a regular exterior paint meant for wood.
