I would use a tan / khaki color for all trim and the aluminum awnings. Then I would paint the front door a lighter tan and put a tan or tan/green/stripe awning over the front door. sorry, I found a darling picture of a brick house almost exactly like yours with a round-top awning over the front door but cannot post it for some Houzz-related malfunction.

Oh, we are cutting back the bush on the left so that you can see that window.

I agree with you - those colors aren't going to work unless you repaint the trim. Also, the cabinets shown on the edge of the picture are a warm color, so you need something warmer than Chantilly Lace. Do you really mean Dove Wing or is it White Dove? Go to the paint store and bring home a couple dozen chips of colors you like and look at them next to your trim and cabinets. Look at all of the whites and off whites in the OC series. I don't know whether you're planning on painting your whole house, but when I moved into my previous house I got the whole chip deck from BM to help when I was looking at colors. I am still using it now for my current house.

It's personal preference but I like the whole thing painted the same color (i.e. framing around the door and sidelights same color as the door. The white framing around my door is vinyl so it is not painted, but you can see that the wood framing on the door and sidelights are the same blue. I suggest getting referrals for a landscape designer (unless you have some talented gardening friends). Even if you don't follow their suggestions plant-by-plant, they can give you great ideas. OR, you can post separately under Landscaping to see what the talented Houzzers suggest. I agree that the front needs something "inviting" but not necessarily a sitting area.
