Does anyone have monochromatic vision?

Who has monochromatic vision?
For all known vertebrates, scotopic vision is monochromatic, since there is typically only one class of rod cell. However, the presence of multiple cone classes contributing to photopic vision enables color vision during daytime conditions. Most humans have three classes of cones, each with a different class of opsin.

What are the 3 types of color blindness?
The different anomalous condition types are protanomaly, which is a reduced sensitivity to red light, deuteranomaly which is a reduced sensitivity to green light (the most common form of colour blindness) and tritanomaly which is a reduced sensitivity to blue light (extremely rare).

Are there any advantages to being color blind?
Shockingly, being colorblind has its advantages. The University of Edinburgh discovered that individuals with red-green colorblindness are better at seeing camouflage. Color can actually impede our ability to detect patterns and textures.
Why can’t you fly on a plane colorblind?
Pilots need to identify different colors to fly successfully. Therefore, pilots are tested for their color perception when they see an Aviation Medical Examiner (AME) for a medical certificate. Your AME will give you a color blindness test. If you fail that test, it’s not necessarily the end of your flying career.
