Blue is my favorite color, what about you?
Blue is also my favorite color. The eye sees blue only when observing light with a dominant wavelength between 450 and 495 nanometres.
Wow I had no idea, I am assuming other colors have different wavelengths, like red for example?
That is correct. The dominant wavelength of red is 625-740 nanometres.
I wonder if you are colorblind if the rods and cones in your eyes can't see those particular wavelengths.
The most common cause of being color blind is inherited and affects development of one or more of the three sets of color sensing cones.
Yes I had a grandfather who was colorblind, luckily I did not get his genes!
Yes you are luck although problems are usually minor and people adapt easily.
