My Huge Rabbit and Flowers in Garden

So today I decided to put my furry rabbit out in its play pen so that it could stretch its legs. Spending time outside with my rabbit today and looking at her fur coat, I thought about why her fur appears to be both black and white. As we learned in physics, my rabbit's fur is white because she reflects back to the viewers eye equal intensities of red, green and blue. The black sections of her fur are black due to the absence of color. Now because of physics, I understand why my rabbit appears to be black and white and why our eyes and brain interpret these mixtures of colors. Also standing in my garden I viewed the orchid plant which we had growing in our yard. This plant seems to bloom at least twice a year. The flowers appear to be red because they reflect back red light while absorbing both green and blue light.

These pictures were taken from last year when I was on the Iolani paddling team. Only now do I realize why exactly the ocean was such a blue color (actually cyan). The ocean appears to be this color because the blue wavelengths are absorbed the least by the ocean water and are therefore reflected and scattered back to the observer's eye. The many particles found in the water contribute to helping the water reflect the blue light. The ocean water is actually not blue....it only appears blue to our eyes due to the scattered blue wavelengths!
