Working with what stays
Compare the porch detail at its actual size
White spindle work and turned posts can read as a single light band from the street. Compare that band against blue, green and light siding rather than choosing colors for tiny details independently.
Use the gable texture deliberately
Fish-scale or shingle-pattern siding adds a second texture. Try it in the main body color first, then compare a restrained change if you want the gable to stand out.
