I’d paint everything that isn’t stone the color of the mortar.

Do not paint the stone it will never look good and always look like painted stone but a color from the stone for the siding will help and new doors that actually suit the style of the house . Take a pic from further back so we can see the whole house too. I would no do the mortar clor unless that is what you like in the stone. Warm climates do not usually dictate the house color .

Would you be able to post a larger photo that shows more of the house. That would help Houzzers to give you the best advice.

Pick a warm tan that goes with the stone. Paint the trim between the stone and siding the same color.
