From velvety purples to fiery reds, many people can see a spectrum of vivid colors via the human eye. Others, however, may have limited hue perception due to certain conditions.
从柔和的紫色到炽热的红色，很多人通过人眼能够看到一系列鲜艳的色彩。然而，也有些人由于某些情况，对色彩的感知能力有限。
Animals, on the other hand, perceive the world through a different lens. Dogs only have two color - sensing cones in their eyes, giving them "dichromatic vision."
另一方面，动物们通过不同的视角感知世界。狗的眼睛里只有两种颜色感知视锥细胞，这使它们具有“二色视觉”。
But what about cats?
但是猫呢？
Our feline companions are capable of navigating low - light environments with ease, but their color vision is not as vibrant as ours. So, how limited is it?
我们的猫咪伙伴能够轻松在弱光环境中活动，但它们的色觉不如我们的鲜艳。那么，它们的色觉限制有多大呢？
What colors can cats see?猫能看到哪些颜色？
The retina uses "cones," a specific type of photoreceptor, to differentiate color, according to the American Academy of Ophthalmology. Human eyes have three types of cones: red - sensing, green - sensing and blue - sensing.
根据美国眼科学会的说法，视网膜利用“视锥细胞”（一种特定类型的光感受器）来区分颜色。人类的眼睛有三种视锥细胞：红色感知、绿色感知和蓝色感知。
Feline eyes also contain the same color - sensing cones as humans, but this doesn't mean our visions are the same, VCA Animal Hospitals reports.
VCA动物医院称，猫的眼睛也含有与人类相同的颜色感知视锥细胞，但这并不意味着我们的视觉是一样的。
Cats are limited in their perception of color. Human eyes have 10 times more cone cells than feline eyes, meaning we can see a larger range of colors than cats, according to Purina.
普瑞纳公司称，猫对颜色的感知能力有限。人类眼睛中的视锥细胞数量是猫眼睛中视锥细胞数量的10倍，这意味着我们能看到的颜色范围比猫更广。
While there isn't an exact answer for which colors cats can see, researchers believe felines can see blues, greens, grays and yellows, Purina reports.
普瑞纳公司报道，虽然对于猫能看到哪些颜色并没有确切答案，但研究人员认为猫能看到蓝色、绿色、灰色和黄色。
What does cat vision look like?猫的视觉是什么样的？
Feline vision can be equated to that of a colorblind person, according to Purina. Cats see "muted tones of blues, yellows, greens and grays." When perceiving reds and pinks, cats might mistake them for green, while purple could be seen as blue.
普瑞纳公司称，猫的视觉可以等同于色盲患者的视觉。猫看到的是“暗淡色调的蓝色、黄色、绿色和灰色”。当感知红色和粉色时，猫可能会把它们错看成绿色，而紫色可能会被看成蓝色。
Cats may not see as many colors as humans but have better light perception.
猫能看到的颜色可能不如人类多，但它们对光线的感知能力更好。
Cats will adjust their eyes during the day, allowing less light to filter in, while their pupils will expand at night to allow for more light, Purina reports. Feline eyes also have more "rods" than human eyes. Rods impact the eyes' light sensitivity and are responsible for peripheral vision, according to the American Academy of Ophthalmology.
普瑞纳公司报道，猫在白天会调整眼睛，让较少的光线透入，而在晚上它们的瞳孔会放大以让更多光线进入。猫的眼睛比人类的眼睛有更多的“视杆细胞”。根据美国眼科学会的说法，视杆细胞影响眼睛对光线的敏感度，并负责周边视觉。
Cats can see up to six times better than the average human in the dark, National Geographic reports.
《国家地理》报道，在黑暗中，猫的视力比普通人好六倍之多。
Can cats see in the dark?猫能在黑暗中看见东西吗？
They can, but don't call it 'night vision.'
它们能，但不要那就是“夜视能力”。
