Final answer:
Individuals with 3) red-green color blindness will have problems distinguishing red and green, as well as colors that contain red or green such as orange. Violet and yellow might also be perceived differently.
Step-by-step explanation:
The client with color blindness will most likely have problems distinguishing colors along the 3) red-green spectrum.
This is due to the most common type of color vision deficiency being red-green color blindness, which affects the ability to differentiate between various shades of red and green.
Thus, the colors that individuals with this form of color blindness typically have trouble seeing are red, green, and, by extension, colors that contain red or green, such as orange.
Violet and yellow may also be affected depending on the type and severity of color blindness, but the most significant issues will usually be seen with red and green or combinations of these colors.
Given the spectrum of visible light, ranging from long-wavelength red to short-wavelength violet, people with normal color vision can distinguish a myriad of colors. However, color blindness can significantly affect this ability.
To clarify, red-green color blindness does not mean that affected individuals cannot see these colors at all, but rather that they may confuse them with other colors or see them as more muted than they actually are.
This condition is notably more common in males than females due to its X-linked inheritance pattern.
