I agree that Latte is very wrong for the brick.

First, rake off the mulch - use it somewhere else in the yard, or if you have suitable spot, pile it up and let it compost down to use later. Or give it away to a neighbor. Then replace with just enough natural hardwood mulch until you are ready to work on the landscape. The goal is to remove the distracting orange color.

Is the porch dyed or just painted? Second goal would be to remove the faded red, for the same reason. So, look into repainting, or re-dying the porch. With those two colors gone, it will be easier to pick out new paint.

That leaves the roof to consider, which seems to be predominantly brown.

I think that a gray-green, or a gray blue that is a little bit on the warm side (to work with the brown on the roof and the front door) are options for the siding and trims. Also, a basic black and gray scheme, with perhaps the door in a pop of color, could be striking. Are you open to painting the door?

I can't suggest specific color names, but you should visit a paint manufacturer's website like Sherwin-Williams, Benjamin Moore, Valspar etc where you can upload a good photo of the house to their visualizer tool (try to get one without all the tree shadows, and where the brick color is clear) and try out various paint colors.
