This is a Plumeria flower, also known as Frangipani. It’s a very popular flower in tropical regions, especially in Hawaii where it’s often used in leis.  

Here’s what makes me confident in this identification:

• Distinct Shape: The flower has five petals with a slightly overlapping, pinwheel-like arrangement.  
• Coloration: The white and yellow petals with pink edges are a common color combination for Plumeria.
• Leathery Leaves: The leaves in the photo appear to be thick and leathery, which is typical of Plumeria plants.
• Location: Plumeria thrives in tropical climates like Hawaii.

There are many different varieties of Plumeria, each with slightly different colors and petal shapes, but the overall characteristics in your photo strongly point to this genus.

I find it really interesting to capture a flower at various stages of blooming, in this case all right on one plant.
