No, colorblind people are unable to fully "appreciate or see" blue light, along with red and green light.
While most colorblind individuals can perceive colors, including blue to some degree, their perception differs from that of someone with normal color vision. They don't truly "see" blue in the same way. The extent to which they can see blue depends on the specific type and severity of their color vision deficiency.
Here's a breakdown:
- The reality of Colorblindness: Colorblindness isn't usually a complete absence of color vision. It's typically a deficiency in how someone perceives colors, impacting their ability to distinguish between certain shades, especially red, green, and blue.
- Different Types of Colorblindness: There are various types of colorblindness. The most common are red-green color deficiencies. Blue colorblindness (tritanopia or tritanomaly) is rarer.
- Impact on Blue Perception: According to provided references, those with colorblindness are unable to fully “appreciate or see” red, green, or blue light. Thus, a person with blue colorblindness might confuse blue with green or gray, or they may have difficulty distinguishing different shades of blue.
