Why does the sun appear yellower or whiter when viewed directly overhead during the day?
Answer
This path involves less distance, resulting in less overall scattering of blue light.
When the sun is overhead, the light travels a shorter distance through the atmosphere, meaning less blue light has been scattered away from the direct line of sight.
