Your inspiration picture is gorgeous. It has 2 colors and 2 materials. Your house has stone, brick, siding/stucco? That's 3, and you're thinking adding 2 colors plus the 2 stones? That won't look as cohesive and natural as your pic. I would stay with one color, dark, as you mentioned. Do your stones and brick match in color?

The house has two materials, (although the pic looks like 3) stone and stucco. The stone will be cream. Struggling with the stucco colors.

hi

you can try cream white and maroon colours for borders
