I would put a flower bed along that low wall on the right side. Because of the low wall the sidewalk almost has the appearance of dissappearing when it gets near the house. In order to appear welcoming it should be wider near the house. I'd widen the walk into a small patio in front of the patio doors and set a few pots with colorful flowers on the patio

Oilpainter's idea of widening the walkway to form a small patio sounds good, too. A large terracotta pot or two might make the orange of the sidewalk less objectionable.

I don't think painting the walkway is the right thing to do. You could end up with a mess of peeling paint. That orange sidewalk does look a little narrow. Could you widen it with bands of something the color of the front walkway?

Anyhow, figure out if that's the color you like and what looks best or what colors you'd like to gravitate toward and how the house color fits it. For example, if the house were a warmer tan color, the terra cotta tile would go better and especially if there were other terra cotta accents. But, if'n you just hate the tile no matter what--and it is a big orange swath in the green grass, which is a little more jarring than if it were amongst warm rock colors, for example-- then you can go ahead with your brainstorming about something else.

As the front yard setback from the street is so big, i might be tempted to do the major shrub and ground cover plantings out by the sidewalk, and create a privacy screen between the house and the street, which would also frame a smaller lawn area adjacent the house as another semi-private space. This might not be in keeping with the way the neighborhood is landscaped, but it can still be a nice way to get more use of your property than leaving the majority of the front yard as lawn entirely open to the street.

I wouldn't necessarily be afraid to leave the foundations devoid of plantings, what law says that every house needs foundation plantings? I do think the low walls are calling out for a different color to contrast with the house, and even if you left the majority of the front yard as lawn, a vividly colorful low planting of something flashy like Russellia equisetiformis massed in front of the low walls, or Heliconia psittacorum look look dramatic, or grouped Agave attenuata or variegated Furcreas.

This is my house color:

Future plans:

-Some type of drive way in the front
-Full view bronze windows with clear glass

Paint the planter walls and eave a darker color and warm up the main house color. White is too clinical looking.

Plant Pygmy Date Palms at the base of the tall palms to bring the eye down to ground level.

Keep the entrance to the courtyard patio area wide as well as widen the walkway from the courtyard patio to the street and straighten it out, not necessary a straight line, but a staggered series of widen offset rectangles.

Of course add some color such as trailing Lantana, colors depend on what the house colors change to.

Inside the low courtyard wall you could add some colorful pot groupings and perhaps a low key contemporary fountain that just peeks over the top of the wall to bekon people's interest towards your front door and create curb appeal.

There are many options here but what you want and your style preference should drive the approach. Front yards sometimes become not so much want you want, but how you want to express yourself to the public.

Think of the entire yard as you did the inside. Dont just plant some shrubs, consider all aspects including creating spaces, walkways, curb appeal, focal point, the overall style or look and then decide on the appropriate materials and colors that would fit your design criteria.
