Let me blow your mind a little.
just finishing a bowl of sour deisel, great
Consider this; leaves are not green in the summer, and they don't turn red/orange in the fall. A red car is not red. Blue water is not blue. Color is in the light. To our eyes, different wavelengths of light appear as colors. A red car is one that has pigments in the paint that reflect wavelengths of light that appear to our eyes as red. Healthy leaves have chlorophyll that absorbs multiple wavelengths of light, but they reflect the wavelength that appears green to us. In the fall, the green chlorophyll dies off and leaves
I got hung up here wondering if you spelled leaves correctly
only the types of chlorophyll that reflect yellows and oranges.
I actually tested this as a science experiment for my son's school's science day. I used red, blue and green LEDs inside a fully enclosed box that was painted flat black on the inside. If I placed a blue ball inside the box and shined the blue light, it appeared blue. But if I shined red or green light on the blue ball, it appeared black. I did the same for a red ball, a yellow ball, and a green ball. The green ball appeared blue in the blue light but black in the red light.
oops, starting to drift here
The reason it appeared blue in the blue light is because green color in the ball is a mixture of blue and yellow. If there is only red light present then the blue, green and yellow balls will not reflect any of the red light from the LED so it appears black.
