There are many colours of white, usually measured by temperature in kelvin. Mid day sun is a different white to late afternoon. With different sun temperatures, you would see different whites, the hotter the star, the bluer or cooler the white. The colder the star, the redder or warmer the white. Our eyes/brains do a great job adjusting white balance so the effect isn’t super obvious until you start comparing warm/neutral/cool whites in interior lighting
