Best Answer: Good question. On average clouds reflect 60% of incoming solar radiation which includes short wave UV. The thicker the cloud the greater the reflection, from 60 - 90%. For thin clouds the albedo, or relection is 30 - 50%, which explains why we can still receive UV on cloudy days.

As sunlight is passing through the atmosphere horizontally above you, the RED light tends to go straight through, while the BLUE light tends to get bounced around (what is called scattered) as described above. When you look up at open sky, you see this scattered light which is mostly BLUE.
