Color


Color Vision

Humans, apes, most old world monkeys, ground squirrels, and many species of fish, birds, and insects have well-developed color vision. However, it's worth noting that 7 or 8 percent of human males are relatively or completely deficient in color vision.
Humans with the most common form of color-blindness and mammals with poor color vision are unable to differentiate between reds and greens. They see the world as a blend of blues, yellows, and greys.

Mammals with limited color vision or none at all include mice, rats, rabbits, cats, and dogs. Nocturnal animals - such as foxes, owls, skunks, and raccoons - whose vision is specialized for dim light seldom have good color vision. By comparison, humans are color-blind in dim light.


Is there a correlation between car color and accidents?

Color is not used to calculate auto insurance rates. Information that is used includes the vehicle's year, make, model, body type and engine size, as well as information about the driver. For instance, you'll see high rates if you own a new blue 400-horsepower Chevrolet Corvette V-8 and have a poor driving record -- but lower rates if you have a red Toyota Camry four-cylinder sedan and a good record.

The Color of Your Nails = The Quality of Your Health

Normally, nail beds are peachy-pink because of a healthy supply of blood into the finger tips and toes. When a diet deficiency or disease is present, sometimes the nail beds become discolored or malformed.

When nails are discolored (a color other than peachy-pink), this may be indicative of a diet deficiency or diabetes, allergies, or other diseases.
Bluish colored nails generally indicate a lack of oxygen in the blood. This discoloration may be caused by lung disease, such as emphysema, or asthma.

Nails with a greenish color may indicate an infection in the nail bed or somewhere else within body.

Bananas get sunburned

If a banana's skin shows dark brown or black spots, these are most likely sunburn spots and not necessarily a sign of over ripeness or rotting. If bananas suffer very long exposure to ultraviolet radiation during their growing period, they develop a tan in their own unique splotchy way.

How "eggplant" got its name

The eggplant, also known as the aubergine in Europe, was named by the English because early specimens were all white and looked like hen's eggs.
Eggplant is related to the tomato and potato. Though commonly thought of as a vegetable, it is actually a fruit ... specifically, a berry. There are many sizes and shapes, ranging in color from white to rich purple.

Note: The term "aubergine" is frequently used to refer the color purple.
