Why will the leaves of a red rose be warmed more than the petals when illuminated with red light?

How does this relate to people in the hot desert wearing white clothes?

Why will the leaves of a red rose be warmed more than the petals when illuminated with red light?
The red light is reflected from the petals. That's why they appear red. The green leaves absorb red light.





White clothes reflect white light, which is all colors combined. Black absorbs all colors.





Note:


The temperature rise is directly proportional to the amount of light absorbed. Heat transfer by radiation.
Reply:Because the green leaves absorb more of the red light,


the red petals reflect more of the red light.
