I like the colour - it looks like an olive green on my screen. Your roof is gray?

I would paint the garage door a darker colour so it doesn't pop out as much.

I can't tell what the yellowish box is to the right of your front door. A planter box? The colour doesn't seem to go with the house colour. Can it be painted? To match your (dark gray?) porch?

For landscaping, consider pruning or replacing the too-large shrub at the corner. Also seems too close to the house. Some more evergreens would give year-round appeal.

Nice-looking house. A few closer pictures of the front door area would be helpful.

I would remove the large shrub at the corner of the house and remove another layer of bottom branches from the pine. I would also continue the mulch from your tree all the way to the front of the house, and use a variety of shrubs/flowers in the mulch areas near the house. Be sure to choose plants that will stay low enough and not block the view of the house. I like your house color, but would paint the garage door either to match the house or in the darker trim color. Paint the brick planter the same color as the steps or the house.

Roof is actually more of a brown, some grey in there too.

I happen to not mind the color. But if you want a change I would maybe do a white with navy or black trim. Otherwise what you have looks nice. Very well kept and neat. I agree the flower box is more of what needs to be swapped than any paint etc.

Consider a flag (wall mounted pole holder to the left of your garage door) to add year round interest and color.
