If the gifts are deductible, the actual cost of the donation is reduced by your tax savings. For example, if you are in the 33% tax bracket, the actual cost of a $100 donation is only $67 ($100 less the $33 tax savings). As your income tax bracket increases, the real cost of your charitable gift decreases, making contributions more attractive for those in higher brackets.
Small particles of dust and pollution in the air can contribute to (and sometimes even enhance) these colors, but the primary cause of a blue sky and orange/red sunsets or sunrises is scattering by the gas molecules that make up our atmosphere.
All Light Is Not the Same. There is a great variety in the color makeup of light that appears white. Direct sunlight at noontime is an almost perfectly balanced light sourceâit contains all colors in nearly equal quantities. But daylight does experience color shifts. The color appearance of objects changes dramatically in early morning or in the shade. Electric light sources can also exhibit variations in color makeup. Incandescent lamps tend to produce more red and yellow light than green and blue, and appear to be âwarmâ in color.
