dundas,
Choosing brck and siding colour was very challenging for us too. I am not sure we got it right, but it might give you some ideas or help you see a red brick with a different siding colour. We chose Brampton Brick Crawford colour in small Queen size. We used a taupe (beige/greige colour) for the board and batten siding, with grey trim. The door is a fiberglass door stained to look like mahogany and there is real wood mahogany trim on the door (not fiberglass trim). Our house is not finished yet, but I have posted a picture where we used Photoshop to show the railing (imagine glass on the railing not mesh). The steps are stone steps and were not installed when picture was taken so we used Photoshop to show the steps too. Sorry, the picture is old, but it is the only one I have that shows what the railing will look like.
Now, your brick has some yellow in it that our brick does not. So, I would not recommend the same colour siding as ours. You could do a beige, but not one that has hints of red undertones like ours does. Grey would also be a colour to explore.
Best of luck deciding! You could also try looking at the Maibac website for ideas of different board and batten siding colours.
