Also:
Many animals are not naturally susceptible to certain types of light. Dogs do not make any difference between red, green, orange and yellow, it's all the same color to them. Shades of red and greeen are not visible for a cat's sight. Such animals like bulls, cows, sheep, pigs, rabbits, and wolves don't ditiguish red color that well. The hedgehog sees only shades of yellow and brown, and that is no accident as this is the color of worms, hedgehog's favorite food, but it doesn't see the red color.The red looks like black to bees, and golden hamsters don't distinguish any colors at all.

HQRP® UV Meter: This meter shows you the level of UV and helps you protect your eyes and skin from negative sunlight effect. The color of the meter changes from very light purple to dark purple depending on the intensity of the UV lighting. The darker the purple color is, the more intense is the UV lighing.
