In getting the right blue takes time and patience with so many variations in shade. Here are some color selections that could help you in the right direction. Please note due to variations of weather and times of day not all color is going to look the same as you see on a swatch. Unfortunately there is going to be some trial and error to get the right Azure Blue for your garage door. For now you can try these colors. In my opinion these colors could work best as an exterior color for your home with the possibility of matching your garage door.
