正常人为三色型色觉,必须有三种原色,才能匹配出光谱中所有的颜色。二色型色觉者,只要有两种原色,即能匹配出光谱中的各种颜色。另一种罕见的一色型色觉者,只需一种原色,只调整其亮度,即能匹配各种颜色。先天性色觉异常一般分类如下: 不正常的三色型色觉(色弱):第一色弱(红色弱)。第二色弱(绿色弱)。第三色弱(兰色弱)。二色型色觉(色盲)。第一色盲(红色盲)。第二色盲(绿色盲)。第三色盲(兰色盲)。一色型色觉(全色盲):杆体型一包 Normal people for three-color color vision, there must be three primary colors, in order to match all the colors of the spectrum. Two-color type of color vision, as long as there are two primary colors, that is, to match the spectrum of various colors. Another rare one-color type of color vision, just a primary color, adjust its brightness, that can match a variety of colors. Congenital color abnormalities are generally classified as follows: Abnormal tricolor (color weakness): the first color weak (red weak). The second color weak (green weak). The third color weak (blue weak). Dichroic color vision (color blindness). First color blind (red blind). Second color blind (green blind). Third color blind (blue color blind). One-color color vision (full color blindness): a rod-shaped bag
