Because the colour of something affect the amount of heat absorption by radiation. Black bodies absorb the most radiation while white bodies absorb the least radiation. (reflecting heat radiation)
Answer 2:The color of an object depends on what color of light it reflects back. A red object absorbs all other colors and reflects red light to your eyes. White is all colors and black is no light. You've probably heard wearing black in the sun makes you very hot. This is because there is no light being reflected back, it's all absorbed. A white shirt is cooler because it reflects all light colors and absorbs much less. Now, what determines the color that is reflected is the atomic composition of the object. Different colors of light have different frequencies, and certain atoms and materials absorb only certain frequencies of electromagnetic radiation (light). So it's not really the color that determines the amount of heat absorbed, it is the composition of the material that determines both the colors of light that are absorbed and thus, how much energy is absorbed. The color is a secondary effect perceived by you, it really doesn't control the heat absorption, it's a result of the atomic structure of the material.

Will dividends and capital gains affect social security payments?
In general, the size of our Social Security retirement checks will depend on your lifetime earnings record and the age that you begin collecting your benefits. If you start collecting payments prior to reaching your Full Retirement Age (FRA) which for the most part is 66 or 67, depending on your year of birth, the amount of any work earnings beyond a certain threshold ($15,480 in 2014) will lead to a reduction in your benefit amount. However, Social Security's definition of earnings counts amounts you earn from working as an employee or net income from your self-employment, but not dividends and/or capital gains from your investments. So in a nutshell, dividends and capital gains do not affect your Social Security payments.
