Why were both the sun and the moon red today?
Smoke.  There was significant smoke across the USA, which attenuated the light from the sun/moon due to increased scattering.  The smoke particles effectively cause the light to reflect in different directions, so you see more colors.

See below for the HMS Smoke Polygons for the day, which clearly shows smoke over your region from the intense smoke/wildfire activity in the Pacific Northwest.  You can also see the NASA Worldview composite of VIIRS visible imagery for the day, with fire locations in red.
