No - colour-blindness is the inability of the brain to interpret correctly colours that the eyes see, or maybe the eyes have a defect in their structure that sends the wrong signals to the brain. Blindness (total?) is when the eyes are unable to send visual signals to the brain at all. Maybe the optic nerve is damaged, or the eyes themselves are damaged - there are various medical reasons for the cause of blindness.

It is not true that color blindness is most common in females. Color blindness is most common in males and approximately 8 percent of men have it.
You can become color blind at any age.
Individuals with color blindness often have a normal male karyotype (46,XY) or female karyotype (46,XX). The genetic basis for color blindness typically involves mutations in genes located on the X chromosome, leading to different types of color vision deficiencies.
If a person with color blindness and dwarfism has a daughter, she would need to inherit the color blindness gene from her father and the dwarfism gene from her mother to be a color-blind dwarf. This would occur 25% of the time if the two conditions are caused by different genes and they independently assort.
